comedi_get_gate_source — get gate for a subdevice

Synopsis

#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);

Status

alpha

Description

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.

Return Value

0 on success, -1 on error.
