unsigned int SIIS_vcduGetHdr	(	const unsigned char *	hdr_buf,
		const unsigned int	hdr_buf_bytes,
		SIIS_Vcdu_Hdr *	hdr_info
	)

Get the information found within a VCDU header.

Build a SIIS_Vcdu_Hdr structure from the information found within a VCDU header.

Parameters:

	hdr_buf	Pointer to buffer containing the VCDU header.
	hdr_buf_bytes	Length of header buffer, in bytes
	hdr_info	Pointer to structure to return header information.

Returns:

A SIIS MSG value.
