From 530014a3cce53e86dce8917e98a4e86d02f176aa Mon Sep 17 00:00:00 2001 From: Mike Buland Date: Thu, 26 Apr 2007 15:06:49 +0000 Subject: Merged Ito and put it in the BU namespace. I should probably clean up the formatting on the comments, some of the lines wrap, but I'm not too worried about it right now. I also fixed up the doxygen config and build.conf files so that everything is building nice and smooth now. --- src/serversocket.h | 31 +++++++++++++++++++++++++++++++ 1 file changed, 31 insertions(+) create mode 100644 src/serversocket.h (limited to 'src/serversocket.h') diff --git a/src/serversocket.h b/src/serversocket.h new file mode 100644 index 0000000..9a26e2d --- /dev/null +++ b/src/serversocket.h @@ -0,0 +1,31 @@ +#ifndef SERVER_SOCKET_H +#define SERVER_SOCKET_H + +#include +#include "fstring.h" +#include "socket.h" + +namespace Bu +{ + /** + * + */ + class ServerSocket + { + public: + ServerSocket( int nPort, int nPoolSize=40 ); + ServerSocket( const FString &sAddr, int nPort, int nPoolSize=40 ); + virtual ~ServerSocket(); + + int accept( int nTimeoutSec, int nTimeoutUSec ); + + private: + void startServer( struct sockaddr_in &name, int nPoolSize ); + + fd_set fdActive; + int nServer; + int nPort; + }; +} + +#endif -- cgit v1.2.3 From dda94f3b53e02e117e6eb5758afa1410e1664c9f Mon Sep 17 00:00:00 2001 From: Mike Buland Date: Tue, 15 May 2007 05:25:19 +0000 Subject: SPtr is now Bu::ified, and the List class now acts the way we think const lists should act, you can't change anything in there.
