Linux Next example of a simple multithreaded mutex

This article is an example of a simple multithreaded mutex in Linux analysis, the need for friends can refer to the following copy code code as follows:

#include <stdio.h>
#include <pthread.h>
pthread_mutex_t device_mutex;
int count=0;
void Thread_func1 ()
{
   while (1)
   {
       Pthread_mutex_lock (&device_mutex);
       printf ("Thread1:%dn", count);
       Pthread_mutex_unlock (&device_mutex);
       count++;
       Sleep (1);
  }
}
void Thread_func2 ()
{
   while (1)
   {
     & nbsp Pthread_mutex_lock (&device_mutex);
       printf ("Thread2:%dn", count);
       Pthread_mutex_unlock (&device_mutex);
       count++;
       Sleep (1);
  }
}
int main ()
{
   pthread_t thread1, thread2;
   pthread_mutex_init (&device_mutex,null);
   if (Pthread_create (&thread1,null, (void*) thread_func1,null) = = 1)
 {
   printf ("Create IP81 Thread error!n");
  exit (1);
 }
 sleep (1);
 if (Pthread_create (&thread2,null, (void *) thread_func2,null) = = 1)
 {
  printf ( "Create Ip81_2 Thread error!n");
  exit (1);
 }
 sleep (1);
 pthread_join (thread1,null);
 pthread_join (thread2,null);
 pthread_mutex_destroy (&device_mutex);
 return 0;
}
