VMI_CMD_REQUESTHW - Syntax

Description: 

VMI_CMD_REQUESTHW is called to request access to the video hardware. VMAN 
processes this command and sends a GHI_CMD_REQUESTHW call 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_REQUESTHW. */
PVOID    pIn;         /*  Pointer to an HWREQIN data structure. */
PVOID    pOut;        /*  NULL; no output structure is needed. */
ULONG    rc;          /*  Return codes. */

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