#include <pthread.h>#include <stdio.h>#include <unistd.h>void* thread_func(void* param){    const char* p = (const char*)param;    pid_t pid = 0;    pthread_t tid = 0;    pid = getpid();    tid = pthread_self();    printf("%s -> %8u %8u\n", p, (unsigned int)pid, (unsigned int)tid);}void* thread_wait_cancel(void* p){    printf("thread wait cancel -> i‘m waitting for cancel\n");    sleep(10000);    printf("if u saw me, there got be something wrong\n");}int main(int argc, char* argv[]){    pthread_t tid = 0;    pthread_create(&tid, NULL, thread_func, (void *)"sub  thread");        pthread_t tid_cancel = 0;    pthread_create(&tid_cancel, NULL, thread_wait_cancel, NULL);    // wait thread tid to exit    pthread_join(tid, NULL);        // cancel a thread    void* stat = 0;    pthread_cancel(tid_cancel);    pthread_join(tid_cancel, &stat);    /* stat = -1 stand for PTHREAD_CANCELED */    printf("cancel thread exit state : %d\n", stat);    // show main thread infomation    thread_func((void *)"main thread");    return 0;}

注意編譯的時候須要加上選項-lpthread。由於pthread不是linu的預設庫，例如以下所看到的：

gcc thr.c -lpthread
