Question

I saw this question Simple example of threading in C++
but my problem is that I want to run this program in windows 32 and it seems that pthread is not recognized in windows!please tell me what is problem?This is my error:
fatal error C1010: unexpected end of file while looking for precompiled header. Did you forget to add ‘#include “StdAfx.h”‘ to your source?(I added #include “StdAfx.h but it still
does not work!)

#include <pthread.h>
#include <stdio.h>
#include <stdlib.h>
#define NUM_THREADS 5

void *PrintHello(void *threadid)
{
  long tid;
  tid = (long)threadid;
  printf("Hello World! It's me, thread #%ld!\n", tid);
  pthread_exit(NULL);
}

int main(int argc, char *argv[])
{
  pthread_t threads[NUM_THREADS];
  int rc;
  long t;
  for(t=0;t<NUM_THREADS;t++)
  {
  printf("In main: creating thread %ld\n", t);
  rc = pthread_create(&threads[t], NULL, PrintHello, (void *)t);
  if (rc){
        printf("ERROR; return code from pthread_create() is %d\n", rc);
        exit(-1);
         }
  }

   /* Last thing that main() should do */
   pthread_exit(NULL);
   }

Because threads are architecture dependent concept, you won’t be able to use pthread without using some kind of a wrapper or use windows-specific threading functions.

You have three choices

1. Use pthread-win32 (wrapper for Win32 thread functions :http://sourceware.org/pthreads-win32/ )
2. Use Windows specific threading functions with #ifdef _WIN32 #else #endif wrapped around
3. Use boost thread library

EDIT: for C1010 error follow the above answer.
