g_mutex_locker_free: @locker: a GMutexLocker
Unlock @locker's mutex. See g_mutex_locker_new() for details.
No memory is freed, it is equivalent to a g_mutex_unlock() call.

g_mutex_locker_new: @mutex: a mutex to lock
Lock @mutex and return a new GMutexLocker. Unlock with g_mutex_locker_free(). Using g_mutex_unlock() on @mutex while a GMutexLocker exists can lead to undefined behaviour.
No allocation is performed, it is equivalent to a g_mutex_lock() call.
This is intended to be used with g_autoptr(). Note that g_autoptr() is only available when using GCC or clang, so the following example will only work with those compilers: |[ typedef struct { ... GMutex mutex; ... } MyObject;
static void my_object_do_stuff (MyObject *self) { g_autoptr(GMutexLocker) locker = g_mutex_locker_new (&self->mutex);
// Code with mutex locked here
if (condition) // No need to unlock return;
// Optionally early unlock g_clear_pointer (&locker, g_mutex_locker_free);
// Code with mutex unlocked here } ]|
Note that it is common for the declared variable to not be used in the scope, which causes some compilers to warn. That can be avoided by using G_GNUC_UNUSED or, since 2.80, [func@.nosp@m.GLib.nosp@m..MUTE.nosp@m.X_AU.nosp@m.TO_LO.nosp@m.CK].
