tmplLockableT()
Functions
void lock()

Locks lockable. If it is already locked by another thread, the current thread will block until it is unlocked by the other thread.

This function can be used even if [glib.thread.Thread.init_] has not yet been called, and, in that case, will do nothing.

Note

unlike [glib.mutex.Mutex.lock], this method recursive, which means a thread can lock lockable several times

(and has to unlock it as many times to actually unlock it).

bool trylock()

Tries to lock lockable. If it is already locked by another thread, then it immediately returns FALSE, otherwise it locks lockable.

This function can be used even if [glib.thread.Thread.init_] has not yet been called, and, in that case, will do nothing.

Note

unlike [glib.mutex.Mutex.lock], this method recursive, which means a thread can lock lockable several times

(and has to unlock it as many times to actually unlock it).

Returns

TRUE if the object has successfully been locked.
void unlock()

Unlocks lockable. This method should not be called if the current does not already holds a lock on lockable (having used [gda.lockable.Lockable.lock] or [gda.lockable.Lockable.trylock]).

This function can be used even if [glib.thread.Thread.init_] has not yet been called, and, in that case, will do nothing.
