class: Private

[22:7] extends: object

The #GPrivate struct is an opaque data structure to represent a thread-local data key. It is approximately equivalent to the pthread_setspecific()/pthread_getspecific() APIs on POSIX and to TlsSetValue()/TlsGetValue() on Windows. If you don't already know why you might want this functionality, then you probably don't need it. #GPrivate is a very limited resource (as far as 128 per program, shared between all libraries). It is also not possible to destroy a #GPrivate after it has been used. As such, it is only ever acceptable to use #GPrivate in static scope, and even then sparingly so. See G_PRIVATE_INIT() for a couple of examples. The #GPrivate structure should be considered opaque. It should only be accessed via the g_private_ functions.

Methods

• Private (Handle = null)

  Creates a new Private 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.
