Hi,
I hope you can help me ;)
I'm working with two threads. One of them is running in an infinite loop
(well, it finishes under certain conditions)
What I want to do is that the infinite loop pauses some times. So I create a
GCond, but I think I didn't understand how it works.
I do something like this:
Thread 1:
for (;;){
g_mutex_lock(my_mutex);
g_cond_wait(my_cond,mi_mutex);
do_some_work_here....
g_mutex_unlock(mi_mutex);
}
The Thread 2 asynchronously toggles the value of a variable between 0 and 1.
When the value is 1, I want the loop runs continuously, but when it is 0,
the loop stops.
if (value==0){
value=1;
g_cond_signal(my_cond);
}
else
value=0;
I've read this:
http://developer.gnome.org/doc/API/2.0/glib/glib-Threads.html#g-thread-create
"The
GCond<http://developer.gnome.org/doc/API/2.0/glib/glib-Threads.html#GCond>struct
is an opaque data structure to represent a condition"
So, the GCond represents the condition, and are not the condition itself...
So when I use g_cond_signal I think I'm telling "the condition is true,
unlock". But in the next iteration, the loop locks again.
How can I tell "The condition is STILL true..."?
Thanks in advance and apologyze if I was not clear explaining my problem.
