STATUS¶
alphaDESCRIPTION¶
This function queries the gate for a subdevice, as set by comedi_set_gate_source. The currently configured gate source will be written to * gate_source. The possible values and their corresponding gates are driver-dependant. If the subdevice does not support configuring its gates on a per-channel basis, then the channel parameter will be ignored. This function is only useable on subdevices that provide support for the INSN_CONFIG_GET_GATE_SOURCE configuration instruction.RETURN VALUE¶
0 on success, -1 on error.AUTHORS¶
