/*
* Name:
* err_null.c
* Purpose:
* Implement the default "err" module.
* Description:
* This file implements the default "err" module for the AST
* library. It is used to deliver error messages if no alternative
* error delivery mechanism is provided.
*
* To provide an alternative mechanism, re-implement this module
* and link your program against the resulting library.

* #include "err.h"
* void astPutErr( int status_value, const char *message )
* Description:
* This function delivers an error message and (optionally) an
* accompanying status value to the user. It may be re-implemented
* in order to deliver error messages in different ways, according
* to the environment in which the AST library is being used.
* Parameters:
* status_value
* The error status value.
* message
* A pointer to a null-terminated character string containing
* the error message to be delivered. This should not contain
* newline characters.
* Notes:
* - This function is documented as "protected" but, in fact, is
* publicly accessible so that it may be re-implemented as
* required.
