Thank you Greg Haerr.
I solve this problem.
I used pthread_mutex_lock().
I writing Code.
first thread code.
=> Event Loop Thread
while (1)
{
pthread_mutex_lock(&test_m);
GrCheckNextEvent(&event);
switch(event.type)
{
case : ......
.......
}
pthread_mutex_unlock(&test_m);
}
second thread code.
=> Update The Screen Func.
UpdateScreen(int x, int y, int w, int h );
{
gc = GrNewGC();
pthread_mutex_lock(&test_m);

GrDestroyGC(gc);
pthread_mutex_unlock(&test_m);

But very slow speed.
I tried to fix for slow speed.
PS. I'm sorry. I poor english.
