New CamelTcpStream class that implements nspr sockets and eventually will
2001-01-14 Jeffrey Stedfast <fejj@helixcode.com> * camel-tcp-stream-ssl.[c,h]: New CamelTcpStream class that implements nspr sockets and eventually will use nss for SSL/TLS. Currently doesn't do any SSL/TLS but it should still work. It's functionally equivalent to CamelTcpStreamRaw at the moment only it uses nspr i/o. * camel-tcp-stream-raw.[c,h]: New CamelTcpStream class that implements native sockets. Should be usable but may have some bugs yet. svn path=/trunk/; revision=7489
