GError: The GError object
Description
GLib provides a standard method of reporting errors from a called function to the calling code.
(This is the same problem solved by exceptions in other languages.)Details
As a transparent-type, a GError is returned to the user as a list
with the following elements:
[object Object],[object Object],[object Object]
The domain is usually retrived via a function of the form NAME_OF_DOMAIN_ERROR().
For example, for GdkPixbuf, the error domain is provided by GDK_PIXBUF_ERROR().References
