Functions to manipulate libalpm packages.

Function Documentation

int alpm_pkg_changelog_close	(	const alpm_pkg_t *	pkg,
		void *	fp
	)

Close a package changelog for reading.

Definition at line 369 of file lib/libalpm/package.c.

References ASSERT, pkg_operations::changelog_close, __alpm_pkg_t::handle, __alpm_pkg_t::ops, and __alpm_handle_t::pm_errno.

Here is the caller graph for this function:

void* alpm_pkg_changelog_open ( alpm_pkg_t * pkg )

Open a package changelog for reading.

Similar to fopen in functionality, except that the returned 'file stream' could really be from an archive as well as from the database.

Parameters:

pkg	the package to read the changelog of (either file or db)

Returns:: a 'file stream' to the package changelog

Definition at line 352 of file lib/libalpm/package.c.

size_t alpm_pkg_changelog_read	(	void *	ptr,
		size_t	size,
		const alpm_pkg_t *	pkg,
		void *	fp
	)

Read data from an open changelog 'file stream'.

Similar to fread in functionality, this function takes a buffer and amount of data to read. If an error occurs pm_errno will be set.

Parameters:

ptr	a buffer to fill with raw changelog data
size	the size of the buffer
pkg	the package that the changelog is being read from
fp	a 'file stream' to the package changelog

Returns:: the number of characters read, or 0 if there is no more data or an error occurred.

		const char *	filename,
		int	full,
		alpm_siglevel_t	level,

	)

Create a package from a file.

If full is false, the archive is read only until all necessary metadata is found. If it is true, the entire archive is read, which serves as a verification of integrity and the filelist can be created. The allocated structure should be freed using alpm_pkg_free().

Parameters:

handle	the context handle
filename	location of the package tarball
full	whether to stop the load after metadata is read or continue through the full archive
level	what level of package signature checking to perform on the package; note that this must be a '.sig' file type verification
pkg	address of the package pointer

Returns:: 0 on success, -1 on error (pm_errno is set accordingly)

Definition at line 264 of file delta.c.

References ASSERT, __alpm_pkg_t::deltas, __alpm_pkg_t::filename, MAX_DELTA_RATIO, and __alpm_pkg_t::size.

int alpm_pkg_vercmp	(	const char *	a,
		const char *	b
	)

Compare two version strings and determine which one is 'newer'.

Returns a value comparable to the way strcmp works. Returns 1 if a is newer than b, 0 if a and b are the same version, or -1 if b is newer than a.

Different epoch values for version strings will override any further comparison. If no epoch is provided, 0 is assumed.

Keep in mind that the pkgrel is only compared if it is available on both versions handed to this function. For example, comparing 1.5-1 and 1.5 will yield 0; comparing 1.5-1 and 1.5-2 will yield -1 as expected. This is mainly for supporting versioned dependencies that do not include the pkgrel.
