Hi, may be this question is offtopic, sorry if this is the case, any way I'll appresiate if someone tell me where to find a good mailing list about Linux programming. Any way, my problem is with the following test code: typedef void*(*ftype)(void*); void *thread_test( void *arg ){ std::cout << "New Thread: " << *((int*)arg) << std::endl; delete arg; } int main(int argc, char *argv[]){ ftype function = thread_test; for ( int i = 0; i < 10; i++ ){ pthread_t thread_handler; int * _ni = new int; *_ni = i; int res = pthread_create( &thread_handler, NULL, function, _ni ); std::cout << "Main Thread" << std::endl; } return EXIT_SUCCESS; } It compiles well, but when I run it, I get a signal 11, at debbug time I notice the signal is generated when the pthread_create is called. Any hint?, any linux-prog mailing list? best reg@rds -- Israel Fdez Cabrera. Usuario Linux: 270292 (http://counter.li.org) israel@xxxxxxxxxx Segurmatica. La Habana, Cuba.
