Simulation support:

This function is mandatory for hardcopy drivers, but may simply return a DEVESC_NOTIMPLEMENTED code. For other drivers, it is simulated by a handling routine in the graphics engine.

Description:

GreEscape DEVESC_GETCP gets a hardcopy data stream that would set the specified code page in the hardcopy device.

Note: This escape code is used only by hardcopy drivers with built-in fonts.

    #define INCL_GRE_DEVICE

    #include <os2.h>

    HDC      hdc;         /*  Device context handle. */

    LONG     lEscape;     /*  DEVESC_GETCP escape code. */

    LONG     cInCount;    /*  The handling routine ignores this parameter. */

    PBYTE    pInData;     /*  The handling routine ignores this parameter. */

    PLONG    pcOutCount;  /*  Pointer to the number of bytes addressed by pOutData. */

    PLONG    pOutData;    /*  Pointer to the buffer in which the handling routine returns the required data. */

    PVOID    pInstance;   /*  Pointer to instance data. */

    ULONG    lFunction;   /*  High-order WORD=flags; low-order WORD=NGreEscape. */

    LONG     rc;          /*  Return Code. */

    rc = GreEscape(hdc, lEscape, cInCount, pInData,

           pcOutCount, pOutData, pInstance, lFunction);
