GC Controller Inputs via named pipes

[IR_]

I posted this in the support forum the other day, but it didn't get any answers so ill post here instead. it might belong here anyways.

I recently saw that as of dolphin revision 4.0-8065, dolphin supports receiving gamecube controller inputs via named pipes. I looked around but could not find any documentation for how one would achieve this.

I then browsed through the code which was helpful and tried this
1) created a dir in /usr/share/dolphin-emu/sys/ with the name "Pipes"
2) created a named pipe called "pipe' in this directory.

then, to test whether the pipe had worked, I started up dolphin, set the controller settings to "Standard Controller" for both port 1 and 2 (the others were at "none") and plugged my controller into the adapter in slot 1. I started up the game (In this case super smash brothers melee for the nintendo gamecube) and did:

Code:

sudo su
echo 'a' > pipe

nothing happened. the a button was not pressed.


If anyone has any knowlodge on named pipes for controlling dolphin, that would be helpful.

tl:dr How do I send GC controller inputs to Dolphin via named pipes?

again, sorry for the double topic. i can delete the other one if need be (or the mods will delete whatever they feel is unnescary) but I really want to find out how to use this feature of dolphin. Thanks dolphin devs for your hard work developing this emulator.
