TPServerSocket
This class implements parallel server sockets. A parallel server
socket waits for requests to come in over the network. It performs
some operation based on that request and then possibly returns a
full duplex parallel socket to the requester. The actual work is
done via the TSystem class (either TUnixSystem, TWin32System or
TMacSystem).
TPServerSocket(Int_t port, Bool_t reuse, Int_t backlog,
Int_t tcpwindowsize) :
TServerSocket(port, reuse, backlog, tcpwindowsize)
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(const char *service, Bool_t reuse, Int_t backlog,
Int_t tcpwindowsize) :
TServerSocket(service, reuse, backlog, tcpwindowsize)
Create a parallel server socket object for a named service. 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.
TSocket* Accept()
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.
