GHI_CMD_QUERYCAPS - Syntax

Description: 

GHI_CMD_QUERYCAPS is mandatory. The GRADD is expected to return its 
capabilities. The returned capabilities are packaged by VMAN and given to 
a Translation Layer. The Translation Layer uses these capabilities to 
decide which GHI_CMD_ functions are sent to the GRADD. 

#include <GRADD.h>

GID      gid;         /*  ID of the GRADD. */
ULONG    ulFunction;  /*  Set equal to GHI_CMD_QUERYCAPS. */
PVOID    pIn;         /*  NULL. */
PVOID    pOut;        /*  Pointer to a CAPSINFO data structure. */
ULONG    rc;          /*  Return codes. */

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