int makeTempFile (const char * prefix, const char fnptr, FD_t** * fdptr)

Return file handle for a temporaray file.

A unique temporaray file path will be generated using rpmGenPath(prefix, '%{_tmppath}/', 'rpm-tmp.XXXXX') where 'XXXXXX' is filled in using rand(3). The file is opened, and the link count and (dev,ino) location are verified after opening. The file name and the open file handle are returned.

Parameters:

prefix: leading part of temp file path

Return values:

fnptr: temp file name (or NULL)
fdptr: temp file handle

Returns: 0 on success

void rpmBuildFileList (Header h, const char *** fileListPtr, int * fileCountPtr)

Retrieve file names from header.

The representation of file names in package headers changed in rpm-4.0. Originally, file names were stored as an array of paths. In rpm-4.0, file names are stored as separate arrays of dirname's and basename's, with a dirname index to associate the correct dirname with each basname. This function is used to retrieve file names independent of how the file names are represented in the package header.

Parameters:

h: header

Return values:

fileListPtr: address of array of file names
fileCountPtr: address of number of files

int rpmHeaderGetEntry (Header h, int_32 tag, int_32 * type, void p, int_32** * c)

Retrieve tag info from header.

This is a 'dressed' entry to headerGetEntry to do: 1) DIRNAME/BASENAME/DIRINDICES -> FILENAMES tag conversions. 2) i18n lookaside (if enabled).

Parameters:

h: header
tag: tag

Return values:

type: address of tag value data type
p: address of pointer to tag value(s)
c: address of number of values

Returns: 0 on success, 1 on bad magic, 2 on error

int rpmPackageGetEntry (void * leadp, Header sigs, Header h, int_32 tag, int_32 * type, void p, int_32** * c)

Retrieve tag info from header.

Yet Another 'dressed' entry to headerGetEntry in order to unify signature/header tag retrieval.

Deprecated: Signature tags are now duplicated into header when installed.

Todo: Eliminate from API.

Parameters:

leadp: rpm lead
h: header
sigs: signatures
tag: tag

Return values:

type: address of tag value data type
p: address of pointer to tag value(s)
c: address of number of values

Returns: 0 on success, 1 on bad magic, 2 on error
