ERROR 5
NAME
error - return an error
SYNOPSIS
size [4] Rerror tag [2] ename [ s ] DESCRIPTION
The
Rerror message
(there is no
Terror ) is used to return an error string
describing the
failure of a transaction.
It replaces the corresponding reply message
that would accompany a successful call; its tag is that
of the failing request.
By convention, clients may truncate error messages after ERRMAX-1 bytes; ERRMAX is defined in <libc.h> .
