gtk-text-buffer-deserialize (buffer content format iter data)

buffer -- a gtk-text-buffer object format is registered with
content -- a gtk-text-buffer object to deserialize into
format -- a gdk-atom as a string with the rich text format to use for deserializing
iter -- a gtk-text-iter insertion point for the deserialized text
data -- a pointer to the data to deserialize

True on success, nil otherwise.

This function deserializes rich text in format and inserts it at iter. The rich text formats to be used must be registered using the gtk-text-buffer-register-deserialize-format or gtk-text-buffer-register-deserialize-tagset functions beforehand.
