O2sLockGuard

#define O2sLockGuard

Automatically unlock the mutex at the end of the current scope.

In a situation where one wants to declare a mutex in a local scope, this "typedef" can be used for that mutex to be unlocked automatically when the variable goes out of scope.

It means this "typedef" can only be used like this:

{
    O2sLockGuard my_mutex = o2s_mutex_lock(...);
    ...
} // <- the mutex will be unlocked at that point
