I use it in RiscLua (http://lua.riscos.org.uk/).

Incidentally, errors in RISC OS are always returned as a
struct { int errno; char errmesg[256]; }, with error numbers
assigned in blocks to registered users, with the base of the block
related to similar registrations for software interrupt codes.
The OS itself can then relate the error number to the module
title, because that is registered too.
