new
Creates a new #GSource structure. The size is specified to allow creating structures derived from #GSource that contain additional data. The size passed in must be at least sizeof (GSource).
The source will not initially be associated with any #GMainContext and must be added to one with g_source_attach() before it will be executed.
Return
the newly-created #GSource.
Parameters
sourceFuncs
structure containing functions that implement the sources behavior.
structSize
size of the #GSource structure to create.
