Happy new year everyone!
I need some info on gthread, and how it interacts with gobject based
structures which get accessed by multiple threads at a time especially
in the respect of deleting objects and signaling and such (I am aware
of the basic locking/mutex/conditioning fun :) )

What kind of s
Let me explain the entire scenario.
I need to be listening to a socket for data from an external program. I do
this using an infinite loop. Once i get the data, i call a function and
after it returns I go back into infinite loop again.
While all this is happening I also need to listen to some sign

your use of threading doesn't make sense. All your threads are within a
lock, so you have three threads (main + two threads) but they can never
execute any instructions in parallel, because they all wait for the
global gdk lock.
Everything you want to
the sample code is:
#include "myheader.h"

If you want people to actually test your code, you do need to show a
*complete* compilable and *minimal* test case.
In general, it's best to avoid threads. For some reason

I haven't seen the code yet. It could be me, but the mailing list software
probably scrubs attachments. Most folks just post as inline text.

Not sure if it's just me, but I can't see the attachment. For things like fseek
and fclose, you might want to look at the gio library
(http://library.gnome.org/devel/gio/stable/) which is included along with glib.

I got the problem!
The thing is, before calling the prepareGrammar() function i am calling a
function, SPI_generateMouseEvent() which modifies the at-spi tree which is
accessed by prepareGrammar, i.e., i was accessing the tree while it was
being modified by another external program. All i need to
I just noticed... the code sometimes works and sometimes doesn't work(the
code doesn't go to completion which kind of confirms that there is thread
lock problem).
There doesn't seem to be an error in other parts of the code because the
code works fine when i comment the file writing part(i.e., pre
It would be *much* easier to help you if you could show us some actual
code that works strangely for you. A minimal but complete sample
program, thanks. Now it is very hard to understand what you mean.

Have you tried a "flush" operation. ie fflush() or g_io_channel_flush()?
Beyond that we would need to see some sort of code example.

Hi,
Within a gnome thread i need to read as well as write to a file. I tried
using the regular fprintf() etc but they don't seem to work.
Can somebody please help me out since I am new to gnome threads.
Thanks in advance.

Tell the thread it has to exit
o through a variable & mutex/condition
o through any form of ipc (maybe simply a pipe())
call g_thread_join() from the main thr
And how to kill the gthread if there is not something like pthread_cancel?

The main thread is the only one that is running inside the gtk_main loop.
The secondary thread is only reading files. So if I do a gtk_main_quit() the
secondary thread will be no longer running because I have not a gtk_main

Wrong, the main thread is not r
hread when it was
created with pthread instead of g_thread?
