pthread_cancel() ফাংশনটি থ্রেড ID দিয়ে একটি নির্দিষ্ট থ্রেড বাতিল করার অনুরোধ পাঠায়।

সিনট্যাক্স: int pthread_cancel(pthread_t th);

উদাহরণ

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

int count = 0;
pthread_t sample_thread;

void* thread_one_func(void* p) {
    while (1) {
        printf("This is thread 1\n");
        sleep(1);
        count++;
        if (count == 5) {
            pthread_cancel(sample_thread);
            pthread_exit(NULL);
        }
    }
}

void* thread_two_func(void* p) {
    sample_thread = pthread_self();
    while (1) {
        printf("This is thread 2\n");
        sleep(2);
    }
}

int main() {
    pthread_t t1, t2;
    pthread_create(&t1, NULL, thread_one_func, NULL);
    pthread_create(&t2, NULL, thread_two_func, NULL);
    pthread_join(t1, NULL);
    pthread_join(t2, NULL);
    return 0;
}
