Simulation support:
This function is mandatory for display drivers. For other drivers, it is simulated by a handling routine in the graphics engine.
Support:
GreCharStr draws a string of character cells from the LVB to the device context.
#define INCL_AVIOP
#include <os2.h>
HDC hdc; /* The device context handle. */
VioPresentationSpace *pVioPS; /* A pointer to the Vio presentation space. */
LPGridRectRef pCharRect;
PVOID pInstance; /* A pointer to instance data. */
ULONG lFunction; /* High-order WORD=flags; low-order WORD=NGreCharStr. */
LONG rc; /* Return codes. */
rc = GreCharStr(hdc, pVioPS, pCharRect, pInstance,
lFunction);
