Title
Body
I need to pass multiple arguments to a function that I would like to call on a separate thread. I've read that the typical way to do this is to define a struct, pass the function a pointer to that, and dereference it for the arguments. However, I am unable to get this to work: #include <stdio.h> #include <pthread.h> struct arg_struct { int arg1; int arg2; }; void *print_the_arguments(void *arguments) { struct arg_struct *args = (struct arg_struct *)args; printf("%d\n", args -> arg1); printf("%d\n", args -> arg2); pthread_exit(NULL); return NULL; } int main() { pthread_t some_thread; struct arg_struct args; args.arg1 = 5; args.arg2 = 7; if (pthread_create(&some_thread, NULL, &print_the_arguments, (void *)&args) != 0) { printf("Uh-oh!\n"); return -1; } return pthread_join(some_thread, NULL); /* Wait until thread is finished */ } The output for this should be: 5 7 But when I run it I actually get: 141921115 -1947974263 Anyone know what I'm doing wrong?
