VMI_CMD_EXTENSION - Syntax

Description: 

VMI_CMD_EXTENSION is called to send an extension command to a GRADD. VMAN 
sends this command directly 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_EXTENSION. */
PVOID    pIn;         /*  Pointer to an HWEXTENSION data structure. */
PVOID    pOut;        /*  Pointer to an extension-specific output structure. */
ULONG    rc;          /*  Return codes. */

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