Parameters

file	pointer to tar header of file
buffer	buffer to store data in
size	size of buffer

Returns

number of bytes copied into buffer

		char *	filename
	)

Get a pointer to a specific file in a tar format file.

Parameters

archive	tar file to process
filename	name of file

Returns

pointer to tar header of filename

int tarGetFilesize

Parameters

file	pointer to tar header of file

Returns

size of file

int tarListFiles	(	struct tar *	archive,
		char *	filelist,
		int	nentries
	)

Get a listing of filenames stored in a tar file.

Parameters

archive	pointer to archive data
filelist	pointer to string array for list of files
nentries	number of entries in filelist array
