2 * Routines for code that can run in GUI and command-line environments to
3 * use to report errors to the user (e.g., I/O errors, or problems with
4 * preference settings).
6 * The application using libwireshark will register error-reporting
7 * routines, and the routines defined here will call the registered
8 * routines. That way, these routines can be called by code that
9 * doesn't itself know whether to pop up a dialog or print something
10 * to the standard error.
