Register an error handling routine for use by the AST error model AST_SETPUTERR
If this function is not called prior to the first error occuring within AST, then the external error handling function selected at link-time (using the ast_link command) will be used. To use an alternative error handler, call this function before using any other AST functions, specifying the external error handling function to be used. This will register the function for future use.
"
null"
routine AST_NULL can be supplied in a subsequent call to astSetPutErr to reset the routine to
the corresponding routine selected at link-time. AST_NULL is defined in the AST_PAR include file. SUBROUTINE PUTERR( STATUS_VALUE, MESSAGE )
STATUS_VALUE = INTEGER (Given) - The error status value.
MESSAGE = CHARACTER ( ) (Given) - The error message to be delivered.
