how to implement threads in c

Pthreads are a simple and effective way of creating a multi-threaded application. 

When a thread is created using pthread_create, both the original thread and the new thread share the same code base and the same memory – it’s just like making two function calls at the same time.

All C programs using pthreads need to include the pthread.h header file.

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

pthread_t thread[2];


static void *function1(void *_){

 int i;
 for(i=0;i<10;i++){
  printf("\nThread1 says=%d",i);
  sleep(1);

}
}

static void *function2(void *_){

 int i;
 for(i=0;i<5;i++){

  printf("\nThread2 says=%d",i);
  sleep(5);
}
}

int main(){

    pthread_create(&thread[0], NULL , function1, NULL);
    pthread_create(&thread[1], NULL , function2, NULL);

    pthread_exit(NULL);
return 1;
}
