GLib.Mutex.lock

### Method

# GLib Mutexlock

#### Declaration [src]

    void
    g_mutex_lock (
      GMutex* mutex
    )

#### Description [src]

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

`GMutex` is neither guaranteed to be recursive nor to be non-recursive. As such, calling `g_mutex_lock()` on a `GMutex` that has already been locked by the same thread results in undefined behaviour (including but not limited to deadlocks).
