comedi_set_gate_source — select gate source for a subdevice
#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); |
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_SRC
configuration instruction.
