Thread Sonlandırma

Thread Sonlandırma

Bir thread, başka bir thread tarafından, ilgili pthread_t id değeri verilmek suretiyle cancel edilebilir:

int pthread_cancel (pthread_t thread);

Örnek: thread_cancel.c

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

void *worker(void *data)
{
    char *name = (char*)data;
    for (int i=0; i<120; i++) {
        usleep(50000);
        printf("Hello from thread %s\n", name);
    }
    printf("Thread %s done...\n", name);
    return NULL;
}

int main(void) {
    pthread_t th1, th2;
    pthread_create(&th1, NULL, worker, "A");
    pthread_create(&th2, NULL, worker, "B");
    sleep(1);
    printf("## Cancelling thread B\n");
    pthread_cancel(th2);
    usleep(100000);
    printf("## Cancelling thread A\n");
    pthread_cancel(th1);
    printf("Exiting from main program\n");
    return 0;
}
