Description: Reference for GObject.type_ensure

### Function

# GObjecttype_ensure

since: 2.34

#### Declaration [src]

    void
    g_type_ensure (
      GType type
    )

#### Description [src]

Ensures that the indicated `type` has been registered with the type system, and its _class_init() method has been run.

In theory, simply calling the type’s _get_type() method (or using the corresponding macro) is supposed take care of this. However, _get_type() methods are often marked `G_GNUC_CONST` for performance reasons, even though this is technically incorrect (since `G_GNUC_CONST` requires that the function not have side effects, which _get_type() methods do on the first call). As a result, if you write a bare call to a _get_type() macro, it may get optimized out by the compiler. Using `g_type_ensure()` guarantees that the type’s _get_type() method is called.
