--- name: "comedi_set_gate_source" section: "3" platform: "linux" package: "libcomedi-dev" version: "0.11.0+5-1.3+b1" release: "Debian 13 (Trixie)" platforms: ["linux"] url: "https://new.carta.tech/comedi_set_gate_source" --- # comedi\_set\_gate\_source(3) select gate source for a subdevice ## NAME comedi\_set\_gate\_source - select gate source for a subdevice ## SYNOPSIS ``` #include ``` **int comedi\_set\_gate\_source(comedi\_t \*** *device***, unsigned int** *subdevice***, unsigned int** *channel***, unsigned int** *gate\_index***, unsigned int** *gate\_source***);** ## STATUS alpha ## DESCRIPTION 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. ## RETURN VALUE 0 on success, -1 on error. ## AUTHORS **David Schleef** \ Author. **Frank Mori Hess** \ Author. **Herman Bruyninckx** \ Author. **Bernd Porr** \ Author. **Ian Abbott** \ Author. **Éric Piel** \ Author. ## COPYRIGHT Copyright © 1998-2003 David Schleef\ Copyright © 2001-2003, 2005, 2008 Frank Mori Hess\ Copyright © 2002-2003 Herman Bruyninckx\ Copyright © 2012 Bernd Porr\ Copyright © 2012 Ian Abbott\ Copyright © 2012, 2015 Éric Piel\ This document is part of Comedilib.
