What is pthread_exit?

#include <stdlib.h> #include <stdio.h> #include <pthread.h> #include <time.h> void* roll_dice() { int value = (rand() % 6) + 1; int* result = malloc(sizeof(int)); *result = value; sleep(2); printf("Thread result: %d\n", value); pthread_exit((void*) result); } int main(int argc, char* argv[]) { int* res; srand(time(NULL)); pthread_t th; if (pthread_create(&th, NULL, &roll_dice, NULL) != 0) { return 1; } // pthread_exit(0); if (pthread_join(th, (void**) &res) != 0) { return 2; } printf("Result: %d\n", *res); free(res); return 0; }
