report_err.h

/* report_err.h
 * Declarations of 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 declared 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.
