comedi_get_gate_source - get gate for a subdevice
#include <comedilib.h> int comedi_get_gate_source(comedi_t * device, unsigned int subdevice, unsigned int channel, unsigned int gate_index, unsigned int * gate_source);
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_SRC configuration instruction.
