Description

GreEscape DEVESC_REGISTER is called by EnDIVE users to register and unregister use with the driver. This function allows each calling process to be uniquely identified by the handle returned on a register operation.

#define INCL_GRE_DEVICE
#include <os2.h>

HDC      hdc;         /*  Device context handle. */

PBYTE    pbInData;    /*  Pointer to VRAMREGISTERIN data structure. */
PLONG    plOutCount;  /*  Number of bytes pointed to by pbOutData. */
PLONG    pbOutData;   /*  Pointer to VRAMREGISTEROUT data structure. */
LONG     rc;          /*  Return Codes. */

rc = GreEscape(hdc, ICODE, lInCount, pbInData,
       plOutCount, pbOutData);
