2 * Declarations of routines for code that can run in GUI and command-line
3 * environments to use to report errors to the user (e.g., I/O errors, or
4 * problems with preference settings).
5 *
6 * The application using libwireshark will register error-reporting
7 * routines, and the routines declared 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.
11 *
