Simulation support:

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

Description:

GreGetStyleRatio stores the style ratio X-direction and Y-direction step values at the location addressed by pRatio.

    #define INCL_GRE_DEVMISC2

    #include <os2.h>

    HDC      hdc;        /*  The device context handle. */

    PBYTE    pRatio;     /*  A pointer to a style ratio value. */

    PVOID    pInstance;  /*  A pointer to instance data. */

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

    BOOL     fSuccess;   /*  Return codes. */

    fSuccess = GreGetStyleRatio(hdc, pRatio, pInstance,

                 lFunction);
