Glib::Mutex Class Reference
[Threads ]
Represents a mutex (mutual exclusion).

List of all members.
Detailed Description
Represents a mutex (mutual exclusion).
It can be used to protect data against shared access. Try to use Mutex::Lock instead of calling lock() and unlock() directly -- it will make your life much easier.
Note: Before creating a Glib::Mutex, Glib::thread_init() has to be called.
Glib::Mutex is not recursive, i.e. a thread will deadlock, if it already has locked the mutex while calling lock() . Use Glib::RecMutex instead, if you need recursive mutexes.
Examples:
thread/thread.cc .

GMutex* Glib::Mutex::gobj
(
)
[inline]
void Glib::Mutex::lock
(
)
Locks the mutex.
If mutex is already locked by another thread, the current thread will block until mutex is unlocked by the other thread.
See also: Mutex::Lock
bool Glib::Mutex::trylock
(
)
Tries to lock the mutex.
If the mutex is already locked by another thread, it immediately returns false.
Otherwise it locks the mutex and returns true.
Returns: Whether the mutex could be locked.
See also: Mutex::Lock
void Glib::Mutex::unlock
(
)
Unlocks the mutex.
If another thread is blocked in a lock() call for this mutex, it will be woken and can lock the mutex itself.
