NAME
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_SOURCE configuration instruction.
RETURN VALUE
0 on success, -1 on error.
