I think is error is in the 4th argument u r passing in this line * pthread_create(&thread1,NULL,(void*)sender,(void*)0);*
The 4th argument is expecting the address of the arguments , but the address he is getting is 0 , which is not granted by OS . Tht address is used by OS I guess . Instead* (void*)0* give it a shot with *NULL *. It should work. -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
