GError {RGtk2} | R Documentation

## 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:

domain

  a numeric vector with one named element that identifies the error domain

code

  an integer code (often an enum value) identifying the specific error type within the domain

message

  a descriptive error message

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()`.
