===Win32===
{{works with|Win32}}
To create a mutex operating system "object":
<
HANDLE hMutex = CreateMutex(NULL, FALSE, NULL);
</
To lock the mutex:
<
WaitForSingleObject(hMutex, INFINITE);
</
To unlock the mutex
<
ReleaseMutex(hMutex);
</
When the program is finished with the mutex:
<
CloseHandle(hMutex);
</
===POSIX===

Creating a mutex:
<c>#include <pthread.h>
pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER;</c>
Locking:
<c>pthread_mutex_lock(&mutex);</c>
Unlocking:
<c>pthread_mutex_unlock(&mutex);</c>
