<!-- ##### SECTION Long_Description ##### -->
<para>
-
+A #GClosure represents a callback supplied by the programmer. It will generally
+comprise a function of some kind and a marshaller used to call it. It is the
+reponsibility of the marshaller to convert the arguments for the invocation
+from #GValue<!-- -->s into a suitable form, perform the callback on the
+converted arguments, and transform the return value back into a #GValue.
+</para>
+<para>
+In the case of C programs, a closure usually just holds a pointer to a function
+and maybe a data argument, and the marshaller converts between #GValue<!-- -->
+and native C types. The GObject library provides the #GCClosure type for this
+purpose. Bindings for other languages need marshallers which
+convert between #GValue<!-- -->s and suitable representations in the runtime
+of the language in order to use functions written in that languages as
+callbacks.

<!-- ##### USER_FUNCTION GCallback ##### -->
<para>
-
+The type used for callback functions in structure definitions and function
+signatures. This doesn't mean that all callback functions must take no
+parameters and return void. The required signature of a callback function
+is determined by the context in which is used (e.g. the signal to which it
+is connected). Use G_CALLBACK() to cast the callback function to a #GCallback.
