Basic example multithreading in C

main.c

#import <stdio.h>
#import <pthread.h>

void *threadFunction(void *arg) {
    // To be executed when called...
}

int main(void) {
    pthread_t *thread;

    // Start and launch the thread
    pthread_create(&thread, NULL, threadFunction);

    // Wait for it to finish
    pthread_join(thread, NULL);

    // Synchronized, thread finished.
    return 0;
}
