VMI_CMD_VRAM - Syntax

Description: 

VMI_CMD_VRAM is called to allocate off-screen video memory. VMAN sends 
this command to the GRADD chain identified by the GRADD ID provided by the 
caller. 

#include <GRADD.h>

GID      gid;         /*  ID of the GRADD. */
ULONG    ulFunction;  /*  Set equal to VMI_CMD_VRAM. */
PVOID    pIn;         /*  Pointer to a VRAMIN data structure. */
PVOID    pOut;        /*  Pointer to a function-specific output data structure. */
ULONG    rc;          /*  Return codes. */

rc = VMIENTRY(gid, ulFunction, pIn, pOut);
