示例C使用volatile变量的函数

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

volatile int stop = 0;

void *runner(void *param) {
    while (!stop) {
        // do some work
    }
    return NULL;
}

int main() {
    pthread_t thread;
    pthread_create(&thread, NULL, runner, NULL);

    // do some other work

    stop = 1;
    pthread_join(thread, NULL);
    return 0;
}
