.SH "DESCRIPTION"
.PP
This function allows selection of a source signal for something on a subdevice other than a gate (which uses
\fBcomedi_set_gate_source\fR) or a clock (which uses
\fBcomedi_set_clock_source\fR)\&. The
\fIother\fR
parameter selects which
\(lqother\(rq
we are configuring, and is driver\-dependent\&. The
\fIsource\fR
parameter selects the source we which to use for the
\(lqother\(rq\&. If the subdevice does not support configuring its
\(lqother\(rq
sources on a per\-channel basis, then the
\fIchannel\fR
parameter will be ignored\&.
.PP
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
\fIother\fR
parameter selects either the A, B, or Z signal, and the
\fIsource\fR
parameter is used to specify which PFI digital input channel the external A, B, or Z signal is physically connected to\&.
.PP
This function is only useable on subdevices that provide support for the
\fBINSN_CONFIG_SET_OTHER_SRC\fR
configuration instruction\&.
.SH "RETURN VALUE"
.PP
0
on success,
\-1
on error\&.
