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
*.
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
gate_sourcechannel parameter will be ignored.
This function is only useable
on subdevices that provide support for the
INSN_CONFIG_GET_GATE_SRC
configuration instruction.
