/* report_message.c
|
|
* Routines for code that can run in GUI and command-line environments to
|
|
* use to report errors and warnings to the user (e.g., I/O errors, or
|
|
* problems with preference settings) if the message should be shown as
|
|
* a GUI error in a GUI environment.
|
|
*
|
|
* The application using libwsutil 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.
