< cpp | thread | lock guard
explicit lock_guard( mutex_type& m );
|
(1) | (since C++11) |
lock_guard( mutex_type& m, std::adopt_lock_t t );
|
(2) | (since C++11) |
lock_guard( const lock_guard& ) = delete;
|
(3) | (since C++11) |
Acquires ownership of the given mutex m
.
1) If m
is not a recursive mutex, requires that the current thread does not own m
. Effectively calls m.lock().
2) Requires that the current thread owns m
.
3) Copy constructor is deleted.
The behavior is undefined if m
is destroyed before the lock_guard
object is.
[edit] Parameters
m | - | mutex to acquire ownership of |
t | - | tag parameter used to select non-locking version of the constructor |
[edit] Exceptions
Throws any exceptions thrown by m.lock()
