static rpmRC ckHeader	(	FD_t	fd,
		const void *	ptr,
		const char **	msg
	)		`[static]`

Check metadata header.

Parameters:

fd	file handle
ptr	metadata header

Return values:

*msg	failure msg

Returns:: rpmRC return code

rpmRC headerCheck	(	pgpDig	dig,
		const void *	uh,
		size_t	uc,
		const char **	msg
	)

Check header consistency, performing headerGet() the hard way.

Check header consistency, performing headerGetEntry() the hard way.

Sanity checks on the header are performed while looking for a header-only digest or signature to verify the blob. If found, the digest or signature is verified.

Parameters:

dig	signature parameters container
uh	unloaded header blob
uc	no. of bytes in blob (or 0 to disable)

Return values:

*msg	signature verification msg

Returns:: RPMRC_OK/RPMRC_NOTFOUND/RPMRC_FAIL
