等待pthread_create完成而不使用pthread_join

#include<stdio.h>
#include <stdlib.h>
#include <pthread.h>

void *my_thread(void *arg) {
    printf("Hello from thread!\n");
    return NULL;
}

int main() {
    pthread_t thread_id;
    int rc;

    rc = pthread_create(&thread_id, NULL, my_thread, NULL);
    if (rc != 0) {
        perror("Failed to create thread");
        exit(1);
    }

    rc = pthread_detach(thread_id);
    if (rc != 0) {
        perror("Failed to detach thread");
        exit(1);
    }

    printf("Hello from main!\n");
    return 0;
}
