nanogui: Thread: THREADSAFE

Hi Greg,

I have a little problem. I am trying to make a small nano-X application. I
have two threads - one sleeping inside GrGetNextEvent and one who is
trying to make the other wake up by calling GrInjectKeyboardEvent. I have
enabled THREADSAFE mode but this results in that  GrInjectKeyboardEvent is
blocked by LOCK(&nxGlobalLock), which is locked by the sleeping
GrGetNextEvent. Is it safe to run this without THREADSAFE mode? If not, is
there another way to make the GrGetNextEvent thread wake up?
Thank you very much in advance!
Best regards,

Malin

It looks like you're going to have to run this without
THREADSAFE.  Both calls eventually call nxFlushReq,
which LOCKs the global lock again, so commenting out
the LOCK in GrInjectKeyboardEvent won't work.

I think you should be OK, since GrInjectKeyboardEvent only
sends data to the server, and never waits for a reply; this is
where the two could otherwise get unsynchronized.

Greg

Sorry Guys.
I hate when a message has no subject to I'm resending this.

I'm not sure if this question will apply to the below comments because it's slightly different.
The problem I'm having is that the thread runs as expected but it's looks like my main loop is halted. It will eventually continue after a few minutes then would halt again.
This repeats several times. Thread safe mode is enabled.

Any thoughts why this occurs?

Thanks,
Robbie

Hi All,
I haven't resolve this problem. I can't seem to find a good doc on pthread that would help me figure out if this is a user configuration error or it's a nanogui problem.
Any ideas?

I believe I have solved this problem. However, I'm looking for a way for an event to interrupt the current thread whatever that may be. Does anyone have any ideas how to use event to handle this?

Thanks,
