perlapi - autogenerated documentation for the perl public APIDESCRIPTION
This file contains the documentation of the perl public API generated by embed.pl, specifically a listing of functions, macros, flags, and variables that may be used by extension writers. The interfaces of any functions that are not listed here are subject to change without notice. For this reason, blindly using functions listed in proto.h is to be avoided when writing extensions. Note that all Perl API global variables must be referenced with the `PL_' prefix. Some macros are provided for compatibility with the older, unadorned names, but this support may be disabled in a future release. The listing is alphabetical, case insensitive. AvFILL Same as `av_len()'. Deprecated, use `av_len()' instead. int AvFILL(AV* av) av_clear Clears an array, making it empty. Does not free the memory used by the array itself. void av_clear(AV* ar) av_extend Pre-extend an array. The `key' is the index to which the array should be extended. void av_extend(AV* ar, I32 key) av_fetch Returns the SV at the specified index in the array. The `key' is the index. If `lval' is set then the fetch will be part of a store. Check that the return value is non-null before dereferencing it to a `SV*'. See the Understanding the Magic of Tied Hashes and Arrays entry in the perlguts manpage for more information on how to use this function on tied arrays. SV** av_fetch(AV* ar, I32 key, I32 lval) av_len Returns the highest index in the array. Returns -1 if the array is empty. I32 av_len(AV* ar) av_make Creates a new AV and populates it with a list of SVs. The SVs are copied into the array, so they may be freed after the call to av_make. The new AV will have a reference count of 1. AV* av_make(I32 size, SV** svp) av_pop Pops an SV off the end of the array. Returns `&PL_sv_undef' if the array is empty. SV* av_pop(AV* ar) av_push Pushes an SV onto the end of the array. The array will grow automatically to accommodate the addition. void av_push(AV* ar, SV* val) av_shift Shifts an SV off the beginning of the array. SV* av_shift(AV* ar) av_store Stores an SV in an array. The array index is specified as `key'. The return value will be NULL if the operation failed or if the value did not need to be actually stored within the array (as in the case of tied arrays). Otherwise it can be dereferenced to get the original `SV*'. Note that the caller is responsible for suitably incrementing the reference count of `val' before the call, and decrementing it if the function returned NULL. See the Understanding the Magic of Tied Hashes and Arrays entry in the perlguts manpage for more information on how to use this function on tied arrays. SV** av_store(AV* ar, I32 key, SV* val) av_undef Undefines the array. Frees the memory used by the array itself. void av_undef(AV* ar) av_unshift Unshift the given number of `undef' values onto the beginning of the array. The array will grow automatically to accommodate the addition. You must then use `av_store' to assign values to these new elements. void av_unshift(AV* ar, I32 num) call_argv Performs a callback to the specified Perl sub. See the perlcall manpage. NOTE: the perl_ form of this function is deprecated. I32 call_argv(const char* sub_name, I32 flags, char** argv) call_method Performs a callback to the specified Perl method. The blessed object must be on the stack. See the perlcall manpage. NOTE: the perl_ form of this function is deprecated. I32 call_method(const char* methname, I32 flags) call_pv Performs a callback to the specified Perl sub. See the perlcall manpage. NOTE: the perl_ form of this function is deprecated. I32 call_pv(const char* sub_name, I32 flags) call_sv Performs a callback to the Perl sub whose name is in the SV. See the perlcall manpage. NOTE: the perl_ form of this function is deprecated. I32 call_sv(SV* sv, I32 flags) CLASS Variable which is setup by `xsubpp' to indicate the class name for a C++ XS constructor. This is always a `char*'. See `THIS'. char* CLASS Copy The XSUB-writer's interface to the C `memcpy' function. The `src' is the source, `dest' is the destination, `nitems' is the number of items, and `type' is the type. May fail on overlapping copies. See also `Move'. void Copy(void* src, void* dest, int nitems, type) croak This is the XSUB-writer's interface to Perl's `die' function. Use this function the same way you use the C `printf' function. See `warn'. void croak(const char* pat, ...) CvSTASH Returns the stash of the CV. HV* CvSTASH(CV* cv) dMARK Declare a stack marker variable, `mark', for the XSUB. See `MARK' and `dORIGMARK'. dMARK; dORIGMARK Saves the original stack mark for the XSUB. See `ORIGMARK'. dORIGMARK; dSP Declares a local copy of perl's stack pointer for the XSUB, available via the `SP' macro. See `SP'. dSP; dXSARGS Sets up stack and mark pointers for an XSUB, calling dSP and dMARK. This is usually handled automatically by `xsubpp'. Declares the `items' variable to indicate the number of items on the stack. dXSARGS; dXSI32 Sets up the `ix' variable for an XSUB which has aliases. This is usually handled automatically by `xsubpp'. dXSI32; ENTER Opening bracket on a callback. See `LEAVE' and the perlcall manpage. ENTER; eval_pv Tells Perl to `eval' the given string and return an SV* result. NOTE: the perl_ form of this function is deprecated. SV* eval_pv(const char* p, I32 croak_on_error) eval_sv Tells Perl to `eval' the string in the SV. NOTE: the perl_ form of this function is deprecated. I32 eval_sv(SV* sv, I32 flags) EXTEND Used to extend the argument stack for an XSUB's return values. Once used, guarrantees that there is room for at least `nitems' to be pushed onto the stack. void EXTEND(SP, int nitems) fbm_compile Analyses the string in order to make fast searches on it using fbm_instr() -- the Boyer-Moore algorithm. void fbm_compile(SV* sv, U32 flags) fbm_instr Returns the location of the SV in the string delimited by `str' and `strend'. It returns `Nullch' if the string can't be found. The `sv' does not have to be fbm_compiled, but the search will not be as fast then. char* fbm_instr(unsigned char* big, unsigned char* bigend, SV* littlesv, U32 flags) FREETMPS Closing bracket for temporaries on a callback. See `SAVETMPS' and the perlcall manpage. FREETMPS; get_av Returns the AV of the specified Perl array. If `create' is set and the Perl variable does not exist then it will be created. If `create' is not set and the variable does not exist then NULL is returned. NOTE: the perl_ form of this function is deprecated. AV* get_av(const char* name, I32 create) get_cv Returns the CV of the specified Perl subroutine. If `create' is set and the Perl subroutine does not exist then it will be declared (which has the same effect as saying `sub name;'). If `create' is not set and the subroutine does not exist then NULL is returned. NOTE: the perl_ form of this function is deprecated. CV* get_cv(const char* name, I32 create) get_hv Returns the HV of the specified Perl hash. If `create' is set and the Perl variable does not exist then it will be created. If `create' is not set and the variable does not exist then NULL is returned. NOTE: the perl_ form of this function is deprecated. HV* get_hv(const char* name, I32 create) get_sv Returns the SV of the specified Perl scalar. If `create' is set and the Perl variable does not exist then it will be created. If `create' is not set and the variable does not exist then NULL is returned. NOTE: the perl_ form of this function is deprecated. SV* get_sv(const char* name, I32 create) GIMME A backward-compatible version of `GIMME_V' which can only return `G_SCALAR' or `G_ARRAY'; in a void context, it returns `G_SCALAR'. Deprecated. Use `GIMME_V' instead. U32 GIMME GIMME_V The XSUB-writer's equivalent to Perl's `wantarray'. Returns `G_VOID', `G_SCALAR' or `G_ARRAY' for void, scalar or array context, respectively. U32 GIMME_V GvSV Return the SV from the GV. SV* GvSV(GV* gv) gv_fetchmeth Returns the glob with the given `name' and a defined subroutine or `NULL'. The glob lives in the given `stash', or in the stashes accessible via @ISA and @UNIVERSAL. The argument `level' should be either 0 or -1. If `level==0', as a side-effect creates a glob with the given `name' in the given `stash' which in the case of success contains an alias for the subroutine, and sets up caching info for this glob. Similarly for all the searched stashes. This function grants `"SUPER"' token as a postfix of the stash name. The GV returned from `gv_fetchmeth' may be a method cache entry, which is not visible to Perl code. So when calling `call_sv', you should not use the GV directly; instead, you should use the method's CV, which can be obtained from the GV with the `GvCV' macro. GV* gv_fetchmeth(HV* stash, const char* name, STRLEN len, I32 level) gv_fetchmethod See the gv_fetchmethod_autoload manpage. GV* gv_fetchmethod(HV* stash, const char* name) gv_fetchmethod_autoload Returns the glob which contains the subroutine to call to invoke the method on the `stash'. In fact in the presence of autoloading this may be the glob for "AUTOLOAD". In this case the corresponding variable $AUTOLOAD is already setup. The third parameter of `gv_fetchmethod_autoload' determines whether AUTOLOAD lookup is performed if the given method is not present: non-zero means yes, look for AUTOLOAD; zero means no, don't look for AUTOLOAD. Calling `gv_fetchmethod' is equivalent to calling `gv_fetchmethod_autoload' with a non-zero `autoload' parameter. These functions grant `"SUPER"' token as a prefix of the method name. Note that if you want to keep the returned glob for a long time, you need to check for it being "AUTOLOAD", since at the later time the call may load a different subroutine due to $AUTOLOAD changing its value. Use the glob created via a side effect to do this. These functions have the same side-effects and as `gv_fetchmeth' with `level==0'. `name' should be writable if contains `':'' or `' '''. The warning against passing the GV returned by `gv_fetchmeth' to `call_sv' apply equally to these functions. GV* gv_fetchmethod_autoload(HV* stash, const char* name, I32 autoload) gv_stashpv Returns a pointer to the stash for a specified package. `name' should be a valid UTF-8 string. If `create' is set then the package will be created if it does not already exist. If `create' is not set and the package does not exist then NULL is returned. HV* gv_stashpv(const char* name, I32 create) gv_stashsv Returns a pointer to the stash for a specified package, which must be a valid UTF-8 string. See `gv_stashpv'. HV* gv_stashsv(SV* sv, I32 create) G_ARRAY Used to indicate array context. See `GIMME_V', `GIMME' and the perlcall manpage. G_DISCARD Indicates that arguments returned from a callback should be discarded. See the perlcall manpage. G_EVAL Used to force a Perl `eval' wrapper around a callback. See the perlcall manpage. G_NOARGS Indicates that no arguments are being sent to a callback. See the perlcall manpage. G_SCALAR Used to indicate scalar context. See `GIMME_V', `GIMME', and the perlcall manpage. G_VOID Used to indicate void context. See `GIMME_V' and the perlcall manpage. HEf_SVKEY This flag, used in the length slot of hash entries and magic structures, specifies the structure contains a `SV*' pointer where a `char*' pointer is to be expected. (For information only--not to be used). HeHASH Returns the computed hash stored in the hash entry. U32 HeHASH(HE* he) HeKEY Returns the actual pointer stored in the key slot of the hash entry. The pointer may be either `char*' or `SV*', depending on the value of `HeKLEN()'. Can be assigned to. The `HePV()' or `HeSVKEY()' macros are usually preferable for finding the value of a key. void* HeKEY(HE* he) HeKLEN If this is negative, and amounts to `HEf_SVKEY', it indicates the entry holds an `SV*' key. Otherwise, holds the actual length of the key. Can be assigned to. The `HePV()' macro is usually preferable for finding key lengths. STRLEN HeKLEN(HE* he) HePV Returns the key slot of the hash entry as a `char*' value, doing any necessary dereferencing of possibly `SV*' keys. The length of the string is placed in `len' (this is a macro, so do not use `&len'). If you do not care about what the length of the key is, you may use the global variable `PL_na', though this is rather less efficient than using a local variable. Remember though, that hash keys in perl are free to contain embedded nulls, so using `strlen()' or similar is not a good way to find the length of hash keys. This is very similar to the `SvPV()' macro described elsewhere in this document. char* HePV(HE* he, STRLEN len) HeSVKEY Returns the key as an `SV*', or `Nullsv' if the hash entry does not contain an `SV*' key. SV* HeSVKEY(HE* he) HeSVKEY_force Returns the key as an `SV*'. Will create and return a temporary mortal `SV*' if the hash entry contains only a `char*' key. SV* HeSVKEY_force(HE* he) HeSVKEY_set Sets the key to a given `SV*', taking care to set the appropriate flags to indicate the presence of an `SV*' key, and returns the same `SV*'. SV* HeSVKEY_set(HE* he, SV* sv) HeVAL Returns the value slot (type `SV*') stored in the hash entry. SV* HeVAL(HE* he) HvNAME Returns the package name of a stash. See `SvSTASH', `CvSTASH'. char* HvNAME(HV* stash) hv_clear Clears a hash, making it empty. void hv_clear(HV* tb) hv_delete Deletes a key/value pair in the hash. The value SV is removed from the hash and returned to the caller. The `klen' is the length of the key. The `flags' value will normally be zero; if set to G_DISCARD then NULL will be returned. SV* hv_delete(HV* tb, const char* key, U32 klen, I32 flags) hv_delete_ent Deletes a key/value pair in the hash. The value SV is removed from the hash and returned to the caller. The `flags' value will normally be zero; if set to G_DISCARD then NULL will be returned. `hash' can be a valid precomputed hash value, or 0 to ask for it to be computed. SV* hv_delete_ent(HV* tb, SV* key, I32 flags, U32 hash) hv_exists Returns a boolean indicating whether the specified hash key exists. The `klen' is the length of the key. bool hv_exists(HV* tb, const char* key, U32 klen) hv_exists_ent Returns a boolean indicating whether the specified hash key exists. `hash' can be a valid precomputed hash value, or 0 to ask for it to be computed. bool hv_exists_ent(HV* tb, SV* key, U32 hash) hv_fetch Returns the SV which corresponds to the specified key in the hash. The `klen' is the length of the key. If `lval' is set then the fetch will be part of a store. Check that the return value is non-null before dereferencing it to a `SV*'. See the Understanding the Magic of Tied Hashes and Arrays entry in the perlguts manpage for more information on how to use this function on tied hashes. SV** hv_fetch(HV* tb, const char* key, U32 klen, I32 lval) hv_fetch_ent Returns the hash entry which corresponds to the specified key in the hash. `hash' must be a valid precomputed hash number for the given `key', or 0 if you want the function to compute it. IF `lval' is set then the fetch will be part of a store. Make sure the return value is non-null before accessing it. The return value when `tb' is a tied hash is a pointer to a static location, so be sure to make a copy of the structure if you need to store it somewhere. See the Understanding the Magic of Tied Hashes and Arrays entry in the perlguts manpage for more information on how to use this function on tied hashes. HE* hv_fetch_ent(HV* tb, SV* key, I32 lval, U32 hash) hv_iterinit Prepares a starting point to traverse a hash table. Returns the number of keys in the hash (i.e. the same as `HvKEYS(tb)'). The return value is currently only meaningful for hashes without tie magic. NOTE: Before version 5.004_65, `hv_iterinit' used to return the number of hash buckets that happen to be in use. If you still need that esoteric value, you can get it through the macro `HvFILL(tb)'. I32 hv_iterinit(HV* tb) hv_iterkey Returns the key from the current position of the hash iterator. See `hv_iterinit'. char* hv_iterkey(HE* entry, I32* retlen) hv_iterkeysv Returns the key as an `SV*' from the current position of the hash iterator. The return value will always be a mortal copy of the key. Also see `hv_iterinit'. SV* hv_iterkeysv(HE* entry) hv_iternext Returns entries from a hash iterator. See `hv_iterinit'. HE* hv_iternext(HV* tb) hv_iternextsv Performs an `hv_iternext', `hv_iterkey', and `hv_iterval' in one operation. SV* hv_iternextsv(HV* hv, char** key, I32* retlen) hv_iterval Returns the value from the current position of the hash iterator. See `hv_iterkey'. SV* hv_iterval(HV* tb, HE* entry) hv_magic Adds magic to a hash. See `sv_magic'. void hv_magic(HV* hv, GV* gv, int how) hv_store Stores an SV in a hash. The hash key is specified as `key' and `klen' is the length of the key. The `hash' parameter is the precomputed hash value; if it is zero then Perl will compute it. The return value will be NULL if the operation failed or if the value did not need to be actually stored within the hash (as in the case of tied hashes). Otherwise it can be dereferenced to get the original `SV*'. Note that the caller is responsible for suitably incrementing the reference count of `val' before the call, and decrementing it if the function returned NULL. See the Understanding the Magic of Tied Hashes and Arrays entry in the perlguts manpage for more information on how to use this function on tied hashes. SV** hv_store(HV* tb, const char* key, U32 klen, SV* val, U32 hash) hv_store_ent Stores `val' in a hash. The hash key is specified as `key'. The `hash' parameter is the precomputed hash value; if it is zero then Perl will compute it. The return value is the new hash entry so created. It will be NULL if the operation failed or if the value did not need to be actually stored within the hash (as in the case of tied hashes). Otherwise the contents of the return value can be accessed using the `He???' macros described here. Note that the caller is responsible for suitably incrementing the reference count of `val' before the call, and decrementing it if the function returned NULL. See the Understanding the Magic of Tied Hashes and Arrays entry in the perlguts manpage for more information on how to use this function on tied hashes. HE* hv_store_ent(HV* tb, SV* key, SV* val, U32 hash) hv_undef Undefines the hash. void hv_undef(HV* tb) isALNUM Returns a boolean indicating whether the C `char' is an ascii alphanumeric character or digit. bool isALNUM(char ch) isALPHA Returns a boolean indicating whether the C `char' is an ascii alphabetic character. bool isALPHA(char ch) isDIGIT Returns a boolean indicating whether the C `char' is an ascii digit. bool isDIGIT(char ch) isLOWER Returns a boolean indicating whether the C `char' is a lowercase character. bool isLOWER(char ch) isSPACE Returns a boolean indicating whether the C `char' is whitespace. bool isSPACE(char ch) isUPPER Returns a boolean indicating whether the C `char' is an uppercase character. bool isUPPER(char ch) items Variable which is setup by `xsubpp' to indicate the number of items on the stack. See the Variable- length Parameter Lists entry in the perlxs manpage. I32 items ix Variable which is setup by `xsubpp' to indicate which of an XSUB's aliases was used to invoke it. See the The ALIAS: Keyword entry in the perlxs manpage. I32 ix LEAVE Closing bracket on a callback. See `ENTER' and the perlcall manpage. LEAVE; looks_like_number Test if an the content of an SV looks like a number (or is a number). I32 looks_like_number(SV* sv) MARK Stack marker variable for the XSUB. See `dMARK'. mg_clear Clear something magical that the SV represents. See `sv_magic'. int mg_clear(SV* sv) mg_copy Copies the magic from one SV to another. See `sv_magic'. int mg_copy(SV* sv, SV* nsv, const char* key, I32 klen) mg_find Finds the magic pointer for type matching the SV. See `sv_magic'. MAGIC* mg_find(SV* sv, int type) mg_free Free any magic storage used by the SV. See `sv_magic'. int mg_free(SV* sv) mg_get Do magic after a value is retrieved from the SV. See `sv_magic'. int mg_get(SV* sv) mg_length Report on the SV's length. See `sv_magic'. U32 mg_length(SV* sv) mg_magical Turns on the magical status of an SV. See `sv_magic'. void mg_magical(SV* sv) mg_set Do magic after a value is assigned to the SV. See `sv_magic'. int mg_set(SV* sv) Move The XSUB-writer's interface to the C `memmove' function. The `src' is the source, `dest' is the destination, `nitems' is the number of items, and `type' is the type. Can do overlapping moves. See also `Copy'. void Move(void* src, void* dest, int nitems, type) New The XSUB-writer's interface to the C `malloc' function. void New(int id, void* ptr, int nitems, type) newAV Creates a new AV. The reference count is set to 1. AV* newAV() Newc The XSUB-writer's interface to the C `malloc' function, with cast. void Newc(int id, void* ptr, int nitems, type, cast) newCONSTSUB Creates a constant sub equivalent to Perl `sub FOO () { 123 }' which is eligible for inlining at compile-time. void newCONSTSUB(HV* stash, char* name, SV* sv) newHV Creates a new HV. The reference count is set to 1. HV* newHV() newRV_inc Creates an RV wrapper for an SV. The reference count for the original SV is incremented. SV* newRV_inc(SV* sv) newRV_noinc Creates an RV wrapper for an SV. The reference count for the original SV is not incremented. SV* newRV_noinc(SV *sv) NEWSV Creates a new SV. A non-zero `len' parameter indicates the number of bytes of preallocated string space the SV should have. An extra byte for a tailing NUL is also reserved. (SvPOK is not set for the SV even if string space is allocated.) The reference count for the new SV is set to 1. `id' is an integer id between 0 and 1299 (used to identify leaks). SV* NEWSV(int id, STRLEN len) newSViv Creates a new SV and copies an integer into it. The reference count for the SV is set to 1. SV* newSViv(IV i) newSVnv Creates a new SV and copies a floating point value into it. The reference count for the SV is set to 1. SV* newSVnv(NV n) newSVpv Creates a new SV and copies a string into it. The reference count for the SV is set to 1. If `len' is zero, Perl will compute the length using strlen(). For efficiency, consider using `newSVpvn' instead. SV* newSVpv(const char* s, STRLEN len) newSVpvf Creates a new SV an initialize it with the string formatted like `sprintf'. SV* newSVpvf(const char* pat, ...) newSVpvn Creates a new SV and copies a string into it. The reference count for the SV is set to 1. Note that if `len' is zero, Perl will create a zero length string. You are responsible for ensuring that the source string is at least `len' bytes long. SV* newSVpvn(const char* s, STRLEN len) newSVrv Creates a new SV for the RV, `rv', to point to. If `rv' is not an RV then it will be upgraded to one. If `classname' is non-null then the new SV will be blessed in the specified package. The new SV is returned and its reference count is 1. SV* newSVrv(SV* rv, const char* classname) newSVsv Creates a new SV which is an exact duplicate of the original SV. SV* newSVsv(SV* old) newSVuv Creates a new SV and copies an unsigned integer into it. The reference count for the SV is set to 1. SV* newSVuv(UV u) newXS Used by `xsubpp' to hook up XSUBs as Perl subs. newXSproto Used by `xsubpp' to hook up XSUBs as Perl subs. Adds Perl prototypes to the subs. Newz The XSUB-writer's interface to the C `malloc' function. The allocated memory is zeroed with `memzero'. void Newz(int id, void* ptr, int nitems, type) Nullav Null AV pointer. Nullch Null character pointer. Nullcv Null CV pointer. Nullhv Null HV pointer. Nullsv Null SV pointer. ORIGMARK The original stack mark for the XSUB. See `dORIGMARK'. perl_alloc Allocates a new Perl interpreter. See the perlembed manpage. PerlInterpreter* perl_alloc() perl_construct Initializes a new Perl interpreter. See the perlembed manpage. void perl_construct(PerlInterpreter* interp) perl_destruct Shuts down a Perl interpreter. See the perlembed manpage. void perl_destruct(PerlInterpreter* interp) perl_free Releases a Perl interpreter. See the perlembed manpage. void perl_free(PerlInterpreter* interp) perl_parse Tells a Perl interpreter to parse a Perl script. See the perlembed manpage. int perl_parse(PerlInterpreter* interp, XSINIT_t xsinit, int argc, char** argv, char** env) perl_run Tells a Perl interpreter to run. See the perlembed manpage. int perl_run(PerlInterpreter* interp) PL_DBsingle When Perl is run in debugging mode, with the -d switch, this SV is a boolean which indicates whether subs are being single-stepped. Single-stepping is automatically turned on after every step. This is the C variable which corresponds to Perl's $DB::single variable. See `PL_DBsub'. SV * PL_DBsingle PL_DBsub When Perl is run in debugging mode, with the -d switch, this GV contains the SV which holds the name of the sub being debugged. This is the C variable which corresponds to Perl's $DB::sub variable. See `PL_DBsingle'. GV * PL_DBsub PL_DBtrace Trace variable used when Perl is run in debugging mode, with the -d switch. This is the C variable which corresponds to Perl's $DB::trace variable. See `PL_DBsingle'. SV * PL_DBtrace PL_dowarn The C variable which corresponds to Perl's $^W warning variable. bool PL_dowarn PL_modglobal `PL_modglobal' is a general purpose, interpreter global HV for use by extensions that need to keep information on a per-interpreter basis. In a pinch, it can also be used as a symbol table for extensions to share data among each other. It is a good idea to use keys prefixed by the package name of the extension that owns the data. HV* PL_modglobal PL_na A convenience variable which is typically used with `SvPV' when one doesn't care about the length of the string. It is usually more efficient to either declare a local variable and use that instead or to use the `SvPV_nolen' macro. STRLEN PL_na PL_sv_no This is the `false' SV. See `PL_sv_yes'. Always refer to this as `&PL_sv_no'. SV PL_sv_no PL_sv_undef This is the `undef' SV. Always refer to this as `&PL_sv_undef'. SV PL_sv_undef PL_sv_yes This is the `true' SV. See `PL_sv_no'. Always refer to this as `&PL_sv_yes'. SV PL_sv_yes POPi Pops an integer off the stack. IV POPi POPl Pops a long off the stack. long POPl POPn Pops a double off the stack. NV POPn POPp Pops a string off the stack. char* POPp POPs Pops an SV off the stack. SV* POPs PUSHi Push an integer onto the stack. The stack must have room for this element. Handles 'set' magic. See `XPUSHi'. void PUSHi(IV iv) PUSHMARK Opening bracket for arguments on a callback. See `PUTBACK' and the perlcall manpage. PUSHMARK; PUSHn Push a double onto the stack. The stack must have room for this element. Handles 'set' magic. See `XPUSHn'. void PUSHn(NV nv) PUSHp Push a string onto the stack. The stack must have room for this element. The `len' indicates the length of the string. Handles 'set' magic. See `XPUSHp'. void PUSHp(char* str, STRLEN len) PUSHs Push an SV onto the stack. The stack must have room for this element. Does not handle 'set' magic. See `XPUSHs'. void PUSHs(SV* sv) PUSHu Push an unsigned integer onto the stack. The stack must have room for this element. See `XPUSHu'. void PUSHu(UV uv) PUTBACK Closing bracket for XSUB arguments. This is usually handled by `xsubpp'. See `PUSHMARK' and the perlcall manpage for other uses. PUTBACK; Renew The XSUB-writer's interface to the C `realloc' function. void Renew(void* ptr, int nitems, type) Renewc The XSUB-writer's interface to the C `realloc' function, with cast. void Renewc(void* ptr, int nitems, type, cast) require_pv Tells Perl to `require' a module. NOTE: the perl_ form of this function is deprecated. void require_pv(const char* pv) RETVAL Variable which is setup by `xsubpp' to hold the return value for an XSUB. This is always the proper type for the XSUB. See the The RETVAL Variable entry in the perlxs manpage. (whatever) RETVAL Safefree The XSUB-writer's interface to the C `free' function. void Safefree(void* src, void* dest, int nitems, type) savepv Copy a string to a safe spot. This does not use an SV. char* savepv(const char* sv) savepvn Copy a string to a safe spot. The `len' indicates number of bytes to copy. This does not use an SV. char* savepvn(const char* sv, I32 len) SAVETMPS Opening bracket for temporaries on a callback. See `FREETMPS' and the perlcall manpage. SAVETMPS; SP Stack pointer.

Returns TRUE if it is, FALSE if not. bool SvTAINTED(SV* sv) SvTAINTED_off Untaints an SV. Be very careful with this routine, as it short-circuits some of Perl's fundamental security features. XS module authors should not use this function unless they fully understand all the implications of unconditionally untainting the value. Untainting should be done in the standard perl fashion, via a carefully crafted regexp, rather than directly untainting variables. void SvTAINTED_off(SV* sv) SvTAINTED_on Marks an SV as tainted. void SvTAINTED_on(SV* sv) SvTRUE Returns a boolean indicating whether Perl would evaluate the SV as true or false, defined or undefined.

UV SvUV(SV* sv) SvUVX Returns the unsigned integer which is stored in the SV, assuming SvIOK is true. UV SvUVX(SV* sv) sv_2mortal Marks an SV as mortal. The SV will be destroyed when the current context ends. SV* sv_2mortal(SV* sv) sv_bless Blesses an SV into a specified package. The SV must be an RV. The package must be designated by its stash (see `gv_stashpv()'). The reference count of the SV is unaffected. SV* sv_bless(SV* sv, HV* stash) sv_catpv Concatenates the string onto the end of the string which is in the SV. Handles 'get' magic, but not 'set' magic. See `sv_catpv_mg'. void sv_catpv(SV* sv, const char* ptr) sv_catpvf Processes its arguments like `sprintf' and appends the formatted output to an SV.

The `rv' argument will be upgraded to an RV. That RV will be modified to point to the new SV. If the `pv' argument is NULL then `PL_sv_undef' will be placed into the SV. The `classname' argument indicates the package for the blessing. Set `classname' to `Nullch' to avoid the blessing. The new SV will be returned and will have a reference count of 1. Do not use with other Perl types such as HV, AV, SV, CV, because those objects will become corrupted by the pointer copy process. Note that `sv_setref_pvn' copies the string while this copies the pointer. SV* sv_setref_pv(SV* rv, const char* classname, void* pv) sv_setref_pvn Copies a string into a new SV, optionally blessing the SV. The length of the string must be specified with `n'.

This can almost be thought of as a reversal of `newSVrv'. See `SvROK_off'. void sv_unref(SV* sv) sv_upgrade Upgrade an SV to a more complex form. Use `SvUPGRADE'. See `svtype'. bool sv_upgrade(SV* sv, U32 mt) sv_usepvn Tells an SV to use `ptr' to find its string value. Normally the string is stored inside the SV but sv_usepvn allows the SV to use an outside string. The `ptr' should point to memory that was allocated by `malloc'. The string length, `len', must be supplied. This function will realloc the memory pointed to by `ptr', so that pointer should not be freed or used by the programmer after giving it to sv_usepvn.

This is always the proper type for the C++ object. See `CLASS' and the Using XS With C++ entry in the perlxs manpage. (whatever) THIS toLOWER Converts the specified character to lowercase. char toLOWER(char ch) toUPPER Converts the specified character to uppercase. char toUPPER(char ch) warn This is the XSUB-writer's interface to Perl's `warn' function.
