<p><a name="index-formatted-messages-1171"></a>
On systems which are based on System V messages of programs (especially
the system tools) are printed in a strict form using the <code>fmtmsg</code>
function.  The uniformity sometimes helps the user to interpret messages
and the strictness tests of the <code>fmtmsg</code> function ensure that the
programmer follows some minimal requirements.
