Function Documentation

int PaWin_WDMKS_QueryFilterMaximumChannelCount	(	void *	wcharDevicePath,
		int	isInput
	)

Query for the maximum number of channels supported by any pin of the specified device. Returns 0 if the query fails for any reason.

Parameters:

	wcharDevicePath	A system level PnP interface path, supplied as a WCHAR unicode string. Declard as void* to avoid introducing a dependency on wchar_t here.
	isInput	A flag specifying whether to query for input (non-zero) or output (zero) channels.
