Here is the caller graph for this function:

alpm_delta_t* _alpm_delta_parse	(	alpm_handle_t *	handle,
		const char *	line
	)

Parses the string representation of a alpm_delta_t object.

This function assumes that the string is in the correct format. This format is as follows: $deltafile $deltamd5 $deltasize $oldfile $newfile

Parameters:

handle	the context handle
line	the string to parse

Returns:: A pointer to the new alpm_delta_t object

Here is the call graph for this function:

off_t _alpm_shortest_delta_path	(	alpm_handle_t *	handle,
		alpm_list_t *	deltas,
		const char *	to,
		alpm_list_t **	path
	)

Calculates the shortest path from one version to another.

The shortest path is defined as the path with the smallest combined size, not the length of the path.

Parameters:

handle	the context handle
deltas	the list of alpm_delta_t * objects that a file has
to	the file to start the search at
path	the pointer to a list location where alpm_delta_t * objects that have the smallest size are placed. NULL is set if there is no path possible with the files available.

Returns:: the size of the path stored, or LONG_MAX if path is unfindable
