Subject: Guile threads vs GTK loop
Date: Sat, 31 Jul 2004 13:26:24 +0200 [thread overview]
Message-ID: <20040731112623.GA21776@feanor> (raw)
Hello
I would like to use Guile (v1.6.4) in GTK app and i want running guile threads
while GTK main event loop is still active. If i execute from C code
begin-thread and return to C code, thread don't get any processor time. I can
call scm_yield() in GTK idle handler (handler called when no events are
available) to give some processor time to scheme threads, but i don't know
whether there are any running threads (i don't want call scm_yield() if there
aren't any).
Does anybody knows:
- How i can ask whether there are any running guile threads?
(To deinstall idle handler where there aren't any.)
- How i can be informed (some hook?) whether any new running guile thread
appeared? (To reinstall idle handler.)
- My Guile-exported C subroutines aren't reentrant. Is there a need to use any
locking? Happen guile thread switches even during call to C subroutines?
