Description: Reference for GLib.Once.init_leave_pointer

### Function

# GLib Onceinit_leave_pointer

since: 2.80

#### Declaration [src]

    void
    g_once_init_leave_pointer (
      void* location,
      gpointer result
    )

#### Description [src]

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

This functions behaves in the same way as g_once_init_leave(), but can be used to initialize pointers (or #guintptr) instead of #gsize.

Available since: 2.80

  The data is owned by the caller of the function.

`result`

  Type: `gpointer`

  New non-`NULL` value for `*location`.

  The argument can be `NULL`.
