Hi,

I have created two threads:Thread 1 and thread 2

In the main thread, i have put up a timer which generates a signal periodically when it expires, which reults in execution going to signal catcher function.

when this function is invoked, under certain condition it goes to thread 1 and under another condition it goes to thread 2.

The problem lies here that when it goes to thread2,i have a loop to process but it doesnt come out of the loop and hence from thread2, even though timer has expired . . where i am going wrong? any advice will be appreciated

Thanks

signals and their handlers are more for inter-processes communication. I'm even not sure you can define a per-thread granularity of signal handling. IMHO you'd better go with mutexes, semaphores and conditions...

ya, i am using mutex and cond variables also but the problem is when it goes into the for loop(runs for million time) of thread2, it runs till it is over, but i want it to come out for a moment and display the thread1 message,
