pthread 정보

POSIX THREAD lib 사용할 때는 -lpthread를 사용해서 컴파일해야 한다.
gcc -o xxx xxx.c -lpthread

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

void* thread_routine(void * arg) {
    printf("[%s] : %d\n", __FILE__, __LINE__);
    return arg;
}

int main(int argc, char** argv) {
    pthread_t thread_id;
    void *thread_result;
    int status;

    status = pthread_create(&thread_id, NULL, thread_routine, NULL);
    if(status != 0) {
        printf("Create thread : %x\n", status);
    }

    status = pthread_join(thread_id, &thread_result);
    if (status!= 0) {
        printf("Thread join : %x\n", status);
    }

    return (thread_result == NULL) ? 0 : 1;
}

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

int cnt = 0;
pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER;

void *Thread1(void *arg) {
    int i, tmp;
    for (i = 0 ; i < 10 ; i++) {
        pthread_mutex_lock(&mutex);

        printf ("Thread1 1\n");
        tmp = cnt;
        usleep(10);
        printf ("Thread1 2\n");
        cnt= tmp + 1;
        pthread_mutex_unlock(&mutex);
        printf ("Thread1 3\n");
    }

    printf ("Thread1 End\n");
    return NULL;
}

void *Thread2(void *arg) {
    int i, tmp;
    for (i = 0 ; i < 10 ; i++) {

        printf ("Thread2 1\n");
        tmp = cnt;

    pthread_create(&thread2, NULL, Thread2, NULL);
    pthread_join(thread1, NULL);
    pthread_join(thread2, NULL);

    printf("%d\n", cnt);
    return 0;
