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.

Constructor & Destructor Documentation

◆ Mutex() [1/2]

Glib::Mutex::Mutex ( )

◆ Mutex() [2/2]

Glib::Mutex::Mutex ( const Mutex & )

delete

◆ ~Mutex()

Glib::Mutex::~Mutex ( )

Member Function Documentation

◆ gobj()

GMutex * Glib::Mutex::gobj ( )

inline

◆ lock()

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

◆ operator=()

Mutex & Glib::Mutex::operator= ( const Mutex & )

delete

◆ trylock()

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

◆ unlock()

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.
