static int checkPassPhrase	(	const char *	passPhrase,
		const int	sigTag
	)			[static]

Definition at line 775 of file signature.c.

static rpmRC checkSize	(	FD_t	fd,
		int	siglen,
		int	pad,
		int	datalen
	)			[inline, static]

Check package size.

Todo:

rpmio: use fdSize rather than fstat(2) to get file size.

Parameters:

	fd	package file handle
	siglen	signature header size
	pad	signature padding
	datalen	length of header+payload

Returns:

rpmRC return code
