static int open_dso	(	const char *	path,
		pid_t *	pidp,
		size_t *	fsizep
	)			[static]

Open a file descriptor to verify file MD5 and size.

Parameters:

path

void rpmfiBuildFNames	(	Header	h,
		rpmTag	tagN,
		const char ***	fnp,
		int *	fcp
	)

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 absolute 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
	tagN	RPMTAG_BASENAMES | PMTAG_ORIGBASENAMES

Return values:

	*fnp	array of file names
	*fcp	number of files
