GLib.Once.init_leave
Description: Reference for GLib.Once.init_leave

### Function

# GLib Onceinit_leave

since: 2.14

#### Declaration [src]

    void
    g_once_init_leave (
      void* location,
      gsize result
    )

#### Description [src]

Counterpart to g_once_init_enter(). Expects a location of a static 0-initialized initialization variable, and an initialization value other than 0. Sets the variable to the initialization value, and releases concurrent threads blocking in `g_once_init_enter()` on this initialization variable.

While `location` has a `volatile` qualifier, this is a historical artifact and the pointer passed to it should not be `volatile`.

Available since: 2.14

#### Parameters

`location`

  Type: `void*`

  Location of a static initializable variable containing 0.

  The argument will be modified by the function.

`result`

  Type: `gsize`

  New non-0 value for `*value_location`.
