GdiGetBatchLimit
The GdiGetBatchLimit function returns 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.
DWORD GdiGetBatchLimit(VOID)
Parameters
This function has no parameters.
Return Values
If the function succeeds, the return value is the batch limit.
If the function fails, the return value is zero. To get extended error
information, call GetLastError.
Remarks
The batch limit is set by using the GdiSetBatchLimit function. Setting the limit to 1 effectively disables batching.
Only GDI drawing functions that return Boolean values can be batched; 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 batches a function call, the function returns TRUE. The actual
return value for the function is reported only if GdiFlush is used to flush the batch.
Note that the batch limit is maintained for each thread separately. In order
to completely disable batching, call GdiSetBatchLimit(1) during the initialization of each thread.
