Simulation support:

This function is mandatory for display drivers. For other drivers, it is simulated by a handling routine in the graphics engine.

Description:

GreDeviceSetAVIOFont loads or deletes an image font used by the AVIO presentation space associated with the device context.

#define INCL_GRE_DEVMISC1
#include <os2.h>

HDC        hdc;        /*  The device context handle. */
PFATTRS    pLogFont;   /*  A pointer to a logical font. */
PBYTE      pFontDef;
LONG       lcid;       /*  Local identifier value of -2, -3, or -4. */
PVOID      pInstance;  /*  A pointer to instance data. */
ULONG      lFunction;  /*  High-order WORD=flags; low-order WORD=NGreDeviceSetAVIOFont. */
BOOL       fSuccess;   /*  Return codes. */

fSuccess = GreDeviceSetAVIOFont(hdc, pLogFont,
             pFontDef, lcid, pInstance, lFunction);
