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