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

Create a parallel 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. 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.

TPServerSocket::TPServerSocket ( const char *  service,

Member Function Documentation

◆ Accept()

TSocket * TPServerSocket::Accept ( UChar_t  Opt = kSrvNoAuth)
virtual

Accept a connection on a parallel server socket.

Returns a full-duplex parallel communication TPSocket 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.
