GreEscape DEVESC_QUERYDRIVERCAPSLIST - Syntax

Simulation support: 

This function is optional for display drivers and has no simulation 
support. 

Description: 

GreEscape DEVESC_QUERYDRIVERCAPSLIST fills the pValueList, pCurrentValue, 
and pDefaultValue in the DRIVERCAPS data structure. The members must be 0 
padded up to the ulValueMemberSize in the pValueList. 

There are three kind of data types that we are supporting at the present 
time-boolean, aggregate of int values, and aggregate of strings. These 
data types are defined as follows: 

   #define  CAPSTYPE_BOOLEAN                   1L 
   #define  CAPSTYPE_AGGREGATE_INT         2L 
   #define  CAPSTYPE_AGGREGATE_STRING    3L

#define INCL_GRE_DEVICE
#include <GRADD.h>

HDC      hdc;         /*  A handle to the device context. */
LONG     lCode;       /*  DEVESC_QUERYDRIVERCAPSLIST */
LONG     lInCount;    /*  Number of bytes pointed to by pbInData. */
PBYTE    pbInData;    /*  Pointer to a DRIVERCAPS data structure. */
PLONG    plOutCount;  /*  Not used. */
PBYTE    pbOutData;   /*  Not used. */
LONG     rc;          /*  Return Code. */

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