NAME

       comedi_set_gate_source - select gate source for a subdevice

SYNOPSIS

       #include <comedilib.h>

       int comedi_set_gate_source(comedi_t * device, unsigned int subdevice,
                                  unsigned int channel, unsigned int gate_index,
                                  unsigned int gate_source);

STATUS

       alpha

DESCRIPTION

       This function selects a gate source for a subdevice. The gate_index parameter selects
       which gate is being configured, should the subdevice have multiple gates. It takes a value
       from 0 to N-1 for a subdevice with N different gates. The gate_source parameter selects
       which signal you wish to use as the gate, and is also driver-dependent. If the subdevice
       does not support configuring its gates on a per-channel basis, then the channel parameter
       will be ignored.

       You may query the gate source with the comedi_get_gate_source function. This function is
       only useable on subdevices that provide support for the INSN_CONFIG_SET_GATE_SOURCE
       configuration instruction.

RETURN VALUE

       0 on success, -1 on error.
