C++ Pthread Create

0 down vote favorite 1 For some reason, pthread_create isn't allowing me to pass a struct as an argument. The issue is not system related, although I have not had a chance to test it on anyone else's box. It simply won't allow me to pass a struct for some reason; it returns error #12. The issue is not with memory. I know 12 is ENOMEM, and create pthread in c example "that should be that", but it's not.. it simply won't accept my struct as a pointer. struct mystruct info; info.website = website; info.file = file; info.type = type; info.timez = timez; for(threadid = 0; threadid < thread_c; threadid++) { // printf("Creating #%ld..\n", threadid); retcode = pthread_create(&threads[threadid], NULL, getstuff, (void *) &info); //void * getstuff(void *threadid); When I ran this code in GDB, for some reason, it didn't return code 12.. but when I run it from the command line, it returns 12. Any ideas? c pthreads share|improve this question edited Dec 31 '11 at 4:18 Jonathan Leffler 439k62510823 asked Dec 31 '11 at 3:58 Saustin 432720 The argument to the thread routine getstuff() is the pointer to &info, which is not a thread ID, despite your comment that its argument is a 'threadid'. You're probably aware of this, but just double checking. –Jonathan Leffler Dec 31 '11 at 4:16 Suppose you pass a null pointer instead of the address of info; you could make info into a global variable since the threads all use the same information - just don't modify it in any of the threads. Do you still run into memory problems?
