NAME gRGBmask - returns the current RGB writemask C SPECIFICATION void gRGBmask(redm, greenm, bluem) short *redm, *greenm, *bluem; PARAMETERS redm expects a pointer to the location into which you want the system to copy the current red writemask value. greenm expects a pointer to the location into which you want the system to copy the current green writemask value. bluem expects a pointer to the location into which you want the system to copy the current blue writemask value. DESCRIPTION gRGBmask gets the current RGB writemask as three 8-bit masks and copies them into the parameters. gRGBmask places masks in the low order 8-bits of the locations.
