GreGetStyleRatio

GreGetStyleRatio stores the style ratio X-direction and Y-direction step values at the location addressed by pRatio.
 * Simulation support: This function is mandatory for display drivers. For other drivers, it is simulated by a handling routine in the graphics engine.

Syntax
GreGetStyleRatio(hdc, pRatio, pInstance, lFunction)

Parameters

 * hdc (HDC) - input:The device context handle.
 * pRatio (PBYTE) - input: A pointer to a style ratio value.
 * The style ratio is defined as a 2-byte value. The low-order byte indicates a step in the X-direction, the high-order byte a step in the Y-direction.


 * pInstance (PVOID) - input: A pointer to instance data.
 * lFunction (ULONG) - input: High-order WORD=flags; low-order WORD=NGreGetStyleRatio.

Returns
On completion, the handling routine must return BOOLEAN (fSuccess). Possible Errors Detected: When an error is detected, the handling routine must call WinSetErrorInfo to post the condition. Error codes for conditions that the handling routine is expected to check include:
 * fSuccess (BOOL) - returns : Return codes.
 * TRUE Successful
 * FALSE Error
 * PMERR_DEV_FUNC_NOT_INSTALLED
 * PMERR_INV_HDC
