NAME
VCTRLsetGTM, VCTRLgetGTM - View control matrix message class typing macros.

SYNOPSIS
#include <sdl.h>

VCTRLsetType(char *header)

VCTRLgetType(char *header)

DESCRIPTION
VCTRLsetGTM inserts into the character string header the tag VCTRLgtm identifying this message as containing a global transformation matrix.

VCTRLgetGTM examines the character string header, and if the VCTRLgtm tag if found, returns a non-zero value. If the VCTRLgtm tag is not found, then zero is returned.

BUGS
VCTRLsetGTM has no way of determining if the header contains sufficient space to hold the tag VCTRLgtm. The results of attempting to store this information beyond the end of the allocated space are undefined.
