/* This API is incredibly limited and unsophisticated. objc_error()

/* 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. */
