GWEN_MDigest_CheckFileTree()

GWENHYWFAR_API int GWEN_MDigest_CheckFileTree	(	GWEN_MDIGEST *	md,
		const char *	folder,
		const char *	checksumFile,
		int	strictCheck,
		uint32_t	pid )

This function verifies the integrity of a given file hierarchy by comparing checksums saved in a given file inside that file tree to the actual checksums of the files in the file tree.

Parameters

md	digest algorithm to use (see GWEN_MDigest_Rmd160_new et al)
folder	folder to check
checkSumFile	name of the file containing the checksums
strictCheck	if !=0 then an error will be returned if there are files in the tree for which there is no corresponding entry in the checksum file
pid	id of the open progress dialog (see GWEN_Gui_ProgressStart)
