/* 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.
