*  Purpose:
*     Implement the "err" module for the DRAMA ERS error system.

*  Description:
*     This file implements an alternative "err" module for the AST
*     library. It is used to deliver error messages through the
*     DRAMA ERS error message system rather than by the default mechanism.

*  Name:
*     astPutErr

*  Purpose:
*     Deliver an error message.

*  Type:
*     Protected function.

*  Synopsis:
*     #include "err.h"
*     void astPutErr( int status, 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
*        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.
