<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>
The <tt><font size=+1>Rerror</font></tt> message (there is no <tt><font size=+1>Terror</font></tt>) 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.
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
By convention, clients may truncate error messages after <tt><font size=+1>ERRMAX−1</font></tt>
bytes; <tt><font size=+1>ERRMAX</font></tt> is defined in <tt><font size=+1><libc.h></font></tt>.<br>
