This patch implements SO_RCVBUF support for apr_socket_opt_set on the unix platform. It also alters the response code on an unknown option to be APR_ENOTIMPL, which IMHO is a lot clearer than "invalid argument" and which would have saved me a hour or so of scratching my head.
Thanks for the patch. I committed the part that implements APR_SO_RCVBUF but not the part that changes the retcode for unrecognized options. Feel free to start a discussion on that on [EMAIL PROTECTED],
which is the proper mailing list for apr-specific issues.
Thanks again!
