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>.
