private

TServerSocket::TServerSocket	(	Int_t	port,
		Bool_t	reuse = kFALSE,
		Int_t	backlog = kDefaultBacklog,
		Int_t	tcpwindowsize = -1
	)

Create a server socket object on a specified port.

Set reuse to true to force reuse of the server socket (i.e. do not wait for the time out to pass). Using backlog one can set the desirable queue length for pending connections. If port is 0 a port scan will be done to find a free port. This option is mutual exlusive with the reuse option. Use tcpwindowsize to specify the size of the receive buffer, it has to be specified here to make sure the window scale option is set (for tcpwindowsize > 65KB and for platforms supporting window scaling). Use IsValid() to check the validity of the server socket. In case server socket is not valid use GetErrorCode() to obtain the specific error value. These values are: 0 = no error (socket is valid) -1 = low level socket() call failed -2 = low level bind() call failed -3 = low level listen() call failed Every valid server socket is added to the TROOT sockets list which will make sure that any open sockets are properly closed on program termination.

TSocket * TServerSocket::Accept ( UChar_t  opt = 0 )

virtual

Accept a connection on a server socket.

Returns a full-duplex communication TSocket object. If no pending connections are present on the queue and nonblocking mode has not been enabled with SetOption(kNoBlock,1) the call blocks until a connection is present. The returned socket must be deleted by the user. The socket is also added to the TROOT sockets list which will make sure that any open sockets are properly closed on program termination. In case of error 0 is returned and in case non-blocking I/O is enabled and no connections are available -1 is returned.

The opt can be used to require client authentication; valid options are

kSrvAuth = require client authentication kSrvNoAuth = force no client authentication

Example: use Opt = kSrvAuth to require client authentication.

Default options are taken from fgAcceptOpt and are initially equivalent to kSrvNoAuth; they can be changed with the static method TServerSocket::SetAcceptOptions(Opt). The active defaults can be visualized using the static method TServerSocket::ShowAcceptOptions().

Receive a TMessage object.

The user must delete the TMessage object. Returns length of message in bytes (can be 0 if other side of connection is closed) or -1 in case of error or -4 in case a non-blocking socket would block (i.e. there is nothing to be read) or -5 if pipe broken or reset by peer (EPIPE || ECONNRESET).
