All info structures can be cast to a `GIBaseInfo`, for instance:

```c
   GIFunctionInfo *function_info = …;
   GIBaseInfo *info = (GIBaseInfo *) function_info;
```

Most [class@GIRepository.Repository] APIs returning a `GIBaseInfo` are
actually creating a new struct; in other words,
[method@GIRepository.BaseInfo.unref] has to be called when done accessing the
data.

`GIBaseInfo` structuress are normally accessed by calling either
[method@GIRepository.Repository.find_by_name],
[method@GIRepository.Repository.find_by_gtype] or
[method@GIRepository.get_info].

```c
GIBaseInfo *button_info =
  gi_repository_find_by_name (NULL, "Gtk", "Button");

// use button_info…

gi_base_info_unref (button_info);

The iterator structure is typically stack allocated, and must have its first
member initialized to `NULL`.  Attributes are arbitrary namespaced key–value
pairs which can be attached to almost any item.  They are intended for use
by software higher in the toolchain than bindings, and are distinct from
normal GIR annotations.

Both the @name and @value should be treated as constants
and must not be freed.

             line="165">Get whether the registered type is a boxed type.

A boxed type is a subtype of the fundamental `G_TYPE_BOXED` type.
It’s a type which has registered a [type@GObject.Type], and which has
associated copy and free functions.

Most boxed types are `struct`s; some are `union`s; and it’s possible for a
boxed type to be neither, but that is currently unsupported by
libgirepository. It’s also possible for a `struct` or `union` to have
associated copy and/or free functions *without* being a boxed type, by virtue
of not having registered a [type@GObject.Type].

This function will return false for [type@GObject.Type]s which are not boxed,
such as classes or interfaces. It will also return false for the `struct`s
associated with a class or interface, which return true from
[method@GIRepository.StructInfo.is_gtype_struct].</doc>

           line="41">`GIRepository` is used to manage repositories of namespaces. Namespaces
are represented on disk by type libraries (`.typelib` files).

The individual pieces of API within a type library are represented by
subclasses of [class@GIRepository.BaseInfo]. These can be found using
methods like [method@GIRepository.Repository.find_by_name] or
[method@GIRepository.Repository.get_info].

You are responsible for ensuring that the lifetime of the
[class@GIRepository.Repository] exceeds that of the lifetime of any of its
[class@GIRepository.BaseInfo]s. This cannot be guaranteed by using internal
references within libgirepository as that would affect performance.

### Discovery of type libraries

`GIRepository` will typically look for a `girepository-1.0` directory
under the library directory used when compiling gobject-introspection. On a
standard Linux system this will end up being `/usr/lib/girepository-1.0`.

It is possible to control the search paths programmatically, using
[method@GIRepository.Repository.prepend_search_path]. It is also possible to
modify the search paths by using the `GI_TYPELIB_PATH` environment variable.
The environment variable takes precedence over the default search path
and the [method@GIRepository.Repository.prepend_search_path] calls.

### Namespace ordering

In situations where namespaces may be searched in order, or returned in a
list, the namespaces will be returned in alphabetical order, with all fully
loaded namespaces being returned before any lazily loaded ones (those loaded
with `GI_REPOSITORY_LOAD_FLAG_LAZY`). This allows for deterministic and
reproducible results.

Similarly, if a symbol (such as a `GType` or error domain) is being searched
for in the set of loaded namespaces, the namespaces will be searched in that
order. In particular, this means that a symbol which exists in two namespaces
will always be returned from the alphabetically-higher namespace. This should
only happen in the case of `Gio` and `GioUnix`/`GioWin32`, which all refer to
the same `.so` file and expose overlapping sets of symbols. Symbols should
always end up being resolved to `GioUnix` or `GioWin32` if they are platform
dependent, rather than `Gio` itself.</doc>

This function cannot fail per se; but for a totally ‘unknown’

The semantics of this function are designed for a dynamic binding,
where in certain cases (such as a function which returns an
interface which may have ‘hidden’ implementation classes), not all
data may be statically known, and will have to be determined from
the [type@GObject.Type] of the object.  An example is
[func@Gio.File.new_for_path] returning a concrete class of
`GLocalFile`, which is a [type@GObject.Type] we see at runtime, but

Multiple calls to this function all contribute to the final
list of paths.

The list of paths is unique to @repository. When a typelib is loaded by the
repository, the list of paths from the @repository at that instant is used
by the typelib for loading its modules.

If the library is not found in the directories configured
in this way, loading will fall back to the system library
path (i.e. `LD_LIBRARY_PATH` and `DT_RPATH` in ELF systems).

In the case where the list or hash table is storing single types rather than

Use this function to ensure that all values are correctly extracted from

This function fills in the appropriate field of @arg with the value extracted

In the case where the list or hash table is storing single types rather than

such as `GPOINTER_TO_INT`.

Use this function to ensure that all values are correctly stuffed into
