class: StaticRecMutex

[23:7] extends: object

A #GStaticRecMutex works like a #GStaticMutex, but it can be locked multiple times by one thread. If you enter it n times, you have to unlock it n times again to let other threads lock it. An exception is the function g_static_rec_mutex_unlock_full(): that allows you to unlock a #GStaticRecMutex completely returning the depth, (i.e. the number of times this mutex was locked). The depth can later be used to restore the state of the #GStaticRecMutex by calling g_static_rec_mutex_lock_full(). In GLib 2.32, #GStaticRecMutex has been deprecated in favor of #GRecMutex. Even though #GStaticRecMutex is not opaque, it should only be used with the following functions. All of the g_static_rec_mutex_* functions can be used even if g_thread_init() has not been called. Then they do nothing, apart from g_static_rec_mutex_trylock(), which does nothing but returning %TRUE.

Methods

• StaticRecMutex (Handle = null)

  Creates a new StaticRecMutex by wrapping a native handle or another wrapper.

  • @p Handle is the native handle or another wrapper whose handle to adopt.

• toNativeHandle (Source)

  Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

  • @p Source is the raw handle, raw buffer, wrapper, or null.
  • @r A raw pointer carrier or null when no pointer is present.

• getLib ()

  Returns the opened native library for this generated wrapper.

  • @r The opened native library.

• handle ()

  Returns the wrapped NativeHandle.

  • @r The wrapped NativeHandle.

• isNull ()

  Returns true when the wrapped handle is null.

  • @r A bool.

• describe ()

  Returns a small string for debugging generated wrappers.

  • @r A string.
