[Rd] getConnection, R_outpstream_st

[Romain Francois]

Hello,

I'm trying to use the limited connections api defined in Rinternals.h. I 
have code that looks like this (inspired from do_serializeToConn) :

SEXP serialize_to_connection( SEXP xp, SEXP connection ){

Rconnection con   ;
struct R_outpstream_st out;
R_pstream_format_t type = R_pstream_binary_format ;
SEXP (*hook)(SEXP, SEXP) = NULL ;
con = getConnection(Rf_asInteger(connection));
R_InitConnOutPStream(&out, con, type, 0, hook, R_NilValue );

return R_NilValue ;
}

The problem I have is that I cannot actually call getConnection since it 
is not part of the api. Is there another way to get the Rconnection that 
is associated with a number.

Many thanks.

Romain
