Acquires ownership of the given mutex m.
1) Effectively calls
m.lock().2) Acquires ownership of the mutex
m without attempting to lock it. The behavior is undefined if the current thread does not hold a non-shared lock (i.e., a lock acquired by lock, try_lock, try_lock_for, or try_lock_until) on m.3) Copy constructor is deleted.
The behavior is undefined if m is destroyed before the lock_guard object is.
Parameters
| m | - | mutex to acquire ownership of |
| t | - | tag parameter used to select non-locking version of the constructor |
Exceptions
1) Throws any exceptions thrown by
m.lock().2) Throws nothing.
