NAME

SYNOPSIS

9       #include <comedilib.h>
10
11       int comedi_get_gate_source(comedi_t * device, unsigned int subdevice,
12                                  unsigned int channel,
13                                  unsigned int gate_index,
14                                  unsigned int * gate_source);

DESCRIPTION

20       This function queries the gate for a subdevice, as set by
21       comedi_set_gate_source. The currently configured gate source will be
22       written to *gate_source. The possible values and their corresponding
23       gates are driver-dependant. If the subdevice does not support
24       configuring its gates on a per-channel basis, then the channel
25       parameter will be ignored.
26
27       This function is only useable on subdevices that provide support for
28       the INSN_CONFIG_GET_GATE_SRC configuration instruction.

RETURN VALUE

31       0 on success, -1 on error.
