GMutex* | gobj () |
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.

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.
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
.
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.
