Use semaphores to build a no-starve mutex, in which any thread that tries to acquire the mutex will eventually obtain it. Use code below.   #include #include #include #include #include "common_threads.h"   typedef __ns_mutex_t { } ns_mutex_t; void ns_mutex_init(ns_mutex_t *m) { } void ns_mutex_acquire(ns_mutex_t *m) { } void ns_mutex_release(ns_mutex_t *m) { } void *worker(void *arg) { return NULL; } int main(int argc, char *argv[]) { printf("parent: begin\n"); printf("parent: end\n"); return 0; }
