VMI_CMD_QUERYMODES - Syntax

Description: 

VMI_CMD_QUERYMODES returns video mode information for a particular GRADD. 
VMAN passes this command directly to the GRADD chain identified by the 
GRADD ID provided by the caller. 

VMI_CMD_QUERYMODES is not typically used by translation layers because the 
VMI_CMD_QUERYCHAININFO function returns the supported modes of all GRADDs, 
as opposed to just one. VMI_CMD_QUERYCHAININFO is the recommended way of 
querying the available modes of all GRADDs in the system. 

#include <GRADD.h>

GID      gid;         /*  ID of the GRADD. */
ULONG    ulFunction;  /*  Set equal to VMI_CMD_QUERYMODES. */
PVOID    pIn;         /*  Pointer that identifies a QUERYMODE operation. */
PVOID    pOut;        /*  Pointer to the pIn operation. */
ULONG    rc;          /*  Return codes. */

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