GdiSetBatchLimit function (wingdi.h)
The GdiSetBatchLimit function sets the maximum number of function calls that can be accumulated in the calling thread's current batch. The system flushes the current batch whenever this limit is exceeded.
Syntax
DWORD GdiSetBatchLimit(
[in] DWORD dw
);
Parameters
[in] dw
Specifies the batch limit to be set. A value of 0 sets the default limit. A value of 1 disables batching.
Return value
If the function succeeds, the return value is the previous batch limit.
If the function fails, the return value is zero.
Remarks
Only GDI drawing functions that return Boolean values can be accumulated in the current batch; calls to any other GDI functions immediately flush the current batch. Exceeding the batch limit or calling the GdiFlush function also flushes the current batch.
When the system accumulates a function call, the function returns TRUE to indicate it is in the batch. When the system flushes the current batch and executes the function for the second time, the return value is either TRUE or FALSE, depending on whether the function succeeds. This second return value is reported only if GdiFlush is used to flush the batch.
