GreGetViewingLimits

GreGetViewingLimits loads the array indicated by prclViewingLimits with the boundaries of the viewing window in graphic model-space coordinates. All boundaries are inclusive.

This function can be hooked by the presentation driver.


 * Simulation support: This function is simulated by a handling routine in the graphics engine.

Syntax
fSuccess = GreGetViewingLimits(hdc, prclViewingLimits, pInstance, lFunction)

Parameters

 * hdc (HDC) - input:Device context handle.
 * prclViewingLimits (PRECTL) - input:Pointer to limits of viewing area (RECTL structure)
 * pInstance (PVOID) - input:Pointer to instance data.
 * lFunction (ULONG) - input:High-order WORD=flags; low-order WORD=NGreGetViewingLimits.

Return Code
This function returns 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: Refer to the "Error Explanations" section in the Presentation Manager Programming Reference for further explanation.
 * fSuccess (BOOL) - returns:Return codes.
 * TRUE Successful
 * FALSE Error
 * PMERR_HDC_BUSY
 * PMERR_INV_HDC
