如何不使用pthread_cancel而杀死线程

http://www.cnblogs.com/no7dw/archive/2012/09/27/2705847.html

During the time I use standalone cross compliers to build my system, I find there is NO pthread_cancel in pthread.h (/home/dengwei/standalone-toolchain/sysroot/usr/include/pthread.h).

Shocked by that, but here comes the solution, by using pthread_kill to send a signal , and adding a signal handler :

#include <pthread.h>

#include <stdio.h>

#include <stdlib.h>

#include <signal.h>

#include <unistd.h>

#include <sys/types.h>

#include <errno.h>

pthread_t pid;

void handle_quit(int signo)

{

    printf("in qq handle sig %d \n", signo);

    pthread_exit(NULL);

    

}

void* test(void *arg)

{

    signal(SIGQUIT,handle_quit );

    for(int i=0;i<100;i++)

    {

        printf("in pthread test \n");

        sleep(1);

    }



}

int main(void)

{

    printf("begin \n");

    pthread_create(&pid, NULL , test, NULL);

    sleep(3);

    if(pthread_kill(pid, 0)!= ESRCH)

    {

        printf("thread %d exists!\n", pid);

        pthread_kill(pid, SIGQUIT);

//        pthread_exit(NULL);//this won't work

        printf("after kill\n");

    }



    sleep(1);

    printf("exit in main\n");
}
