-/* Error handling
-
- Call objc_error() or objc_verror() to record an error; this error
- routine will generally exit the program but not necessarily if the
- user has installed his own error handler.
-
- Call objc_set_error_handler to assign your own function for
- handling errors. The function should return YES if it is ok
- to continue execution, or return NO or just abort if the
- program should be stopped. The default error handler is just to
- print a message on stderr.
-
- The error handler function should be of type objc_error_handler
- The first parameter is an object instance of relevance.
- The second parameter is an error code.
- The third parameter is a format string in the printf style.
- The fourth parameter is a variable list of arguments. */
