Description

GreOpenDC creates an output device context (DC). The new device context inherits the current code page of the process that created it.

This function is supported by the graphics engine.

HDC             hdc;        /*  Device context handle. */
ULONG           ulType;     /*  Type of DC being opened. */
PSZ             pszToken;   /*  This parameter is ignored by the graphics engine. */
LONG            cData;      /*  Number of elements in the data structure. */
PDEVOPENDATA    pszData;    /*  Pointer to data structure. */
PVOID           pInstance;  /*  Pointer to instance data. */
ULONG           lFunction;  /*  High-order WORD=flags; low-order WORD=NGreOpenDC. */
HDC             rc;         /*  Return codes. */

rc = GreOpenDC(hdc, ulType, pszToken, cData,
       pszData, pInstance, lFunction);
