### GHI_CMD_SHOWPTR - Syntax

Description:

GHI_CMD_SHOWPTR is optional and sets the visibility state of the pointer. The fShow field of the pIn data packet determines the visibility state.

The GRADD can return this function call to VMAN for simulation.

    #include <GRADD.h>

    GID      gid;         /*  ID of the GRADD. */

    ULONG    ulFunction;  /*  Set equal to GHI_CMD_SHOWPTR. */

    PVOID    pIn;         /*  Pointer to an HWSHOWPTRIN data structure. */

    PVOID    pOut;        /*  NULL; no output structure needed. */

    ULONG    rc;          /*  Return codes. */

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