NAME

       comedi_set_other_source - select source signal for something other than a gate or clock

SYNOPSIS

       #include <comedilib.h>

       int comedi_set_other_source(comedi_t * device, unsigned int subdevice,
                                   unsigned int channel, unsigned int other,
                                   unsigned int source);

STATUS

       alpha

DESCRIPTION

       This function allows selection of a source signal for something on a subdevice other than
       a gate (which uses comedi_set_gate_source) or a clock (which uses
       comedi_set_clock_source). The other parameter selects which “other” we are configuring,
       and is driver-dependent. The source parameter selects the source we which to use for the
       “other”. If the subdevice does not support configuring its “other” sources on a
       per-channel basis, then the channel parameter will be ignored.

       As an example, this function is used to select which PFI digital input channels should be
       used as the A/B/Z signals when running a counter on an NI M-Series board as a quadrature
       encoder. The other parameter selects either the A, B, or Z signal, and the source
       parameter is used to specify which PFI digital input channel the external A, B, or Z
       signal is physically connected to.

       This function is only useable on subdevices that provide support for the
       INSN_CONFIG_SET_OTHER_SOURCE configuration instruction.

RETURN VALUE

       0 on success, -1 on error.
