The <glob.h> header shall define the structures and symbolic
constants used by the glob() function.
The structure type glob_t shall contain at least the following
members:
size_t gl_pathc Count of paths matched by pattern.
char **gl_pathv Pointer to a list of matched pathnames.
size_t gl_offs Slots to reserve at the beginning of gl_pathv.
The following constants shall be provided as values for the flags
argument:
GLOB_APPEND
Append generated pathnames to those previously obtained.
GLOB_DOOFFS
Specify how many null pointers to add to the beginning of gl_pathv.
GLOB_ERR
Cause glob() to return on error.
GLOB_MARK
Each pathname that is a directory that matches pattern has a
slash appended.
GLOB_NOCHECK
If pattern does not match any pathname, then return a list consisting
of only pattern.
GLOB_NOESCAPE
Disable backslash escaping.
GLOB_NOSORT
Do not sort the pathnames returned.
The following constants shall be defined as error return values:
GLOB_ABORTED
The scan was stopped because GLOB_ERR was set or (*errfunc)()
returned non-zero.
GLOB_NOMATCH
The pattern does not match any existing pathname, and GLOB_NOCHECK
was not set in flags.
GLOB_NOSPACE
An attempt to allocate memory failed.
GLOB_NOSYS
Reserved.
The following shall be declared as functions and may also be defined
as macros. Function prototypes shall be provided.
int glob(const char *restrict, int, int (*)(const char *, int),
glob_t *restrict);
void globfree (glob_t *);
The implementation may define additional macros or constants using
names beginning with GLOB_.
The following sections are informative.
APPLICATION USAGE
None.
RATIONALE
None.
FUTURE DIRECTIONS
None.
