| 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.
| wcharDevicePath | A system level PnP interface path, supplied as a WCHAR unicode string. Declared 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. |
