Find the AS for given ASP + optional routing context IE. 

if rctx\+\_\+ie == NULL, we assume that this ASP is only part of a single AS; if rctx\+\_\+ie is given, then we look-\/up the ASP based on the routing context, and verify that this ASP is part of it. 
\begin{DoxyParams}[1]{Parameters}
\mbox{\texttt{ out}}  & {\em as} & caller-\/provided address-\/of-\/pointer to store the found AS \\
\hline
\mbox{\texttt{ in}}  & {\em asp} & ASP for which we want to look-\/up the AS \\
\hline
\mbox{\texttt{ in}}  & {\em rctx\+\_\+ie} & routing context IE (may be NULL) to use for look-\/up \\
\hline
\end{DoxyParams}
\begin{DoxyReturn}{Returns}
0 in case of success; \{M3\+UA,SUA\}\+\_\+\+ERR\+\_\+$\ast$ code in case of error. 
\end{DoxyReturn}
