<!-- ##### FUNCTION g_type_check_flags ##### -->
<para>
Determines whether a given set of #GTypeFlags and #GTypeFundamentalFlags
are set for @type.
</para>

@type: 	  The type to check for flags.
@flags:   Bitwise combination of #GTypeFlags and #GTypeFundamentalFlags.
@Returns: #TRUE if all @flags are set for @type, #FALSE otherwise.

<!-- ##### FUNCTION g_type_class_get_private ##### -->
<para>

</para>

@klass: 
@private_type: 
@Returns: 

<!-- ##### FUNCTION g_type_instance_is_a ##### -->
<para>
Determines if @instance adheres to the interface exported
by @iface_type. @iface_type is either a type that @instance
is derived from, or an interface type that is supported by
the anchestry of @instance.
</para>

@instance: 	A valid #GTypeInstance structure.
@iface_type: 	A #GType value.
@Returns: 	#TRUE if @instance conforms to @iface_type, #FALSE otherwise.

<!-- ##### FUNCTION g_type_value_is_a ##### -->
<para>
Determines if @value is a #GValue whose type conforms to @type.
</para>

@value: 	  A valid #GValue structure.
@type:    A #GType value.
@Returns: #TRUE if @value is a #GValue of @type or #FALSE if not.
