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

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.

Deprecated:

Use Glib::Threads::Mutex instead.

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.

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.
