Error Message Service
This document describes the Error Message Service, EMS, and its use in system software. The purpose of EMS is to provide facilities for constructing and storing error messages for future delivery to the user – usually via the Starlink Error Reporting System, ERR (see SUN/104). EMS can be regarded as a simplified version of ERR without the binding to any software environment (e.g. for message output or access to the parameter and data systems). The routines in this library conform to the error reporting conventions described in SUN/104. A knowledge of these conventions, and of the ADAM system (see SG/4), is assumed in what follows.
This document is intended for Starlink systems programmers and can safely be ignored by applications programmers and users.
