Constructor & Destructor Documentation

◆ TPSocket() [1/7]

TPSocket::TPSocket ( TSocket pSockets[],
Int_t  size 
)
private

Create a parallel socket. This ctor is called by TPServerSocket.

private

◆ TPSocket() [3/7]

TPSocket::TPSocket ( TInetAddress  addr,
const char *  service,
Int_t  size,
Int_t  tcpwindowsize = -1 
)

Create a parallel socket.

Connect to the named service at address addr. 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). Returns when connection has been accepted by remote side. Use IsValid() to check the validity of the socket. Every socket is added to the TROOT sockets list which will make sure that any open sockets are properly closed on program termination.

Definition at line 47 of file TPSocket.cxx.

◆ TPSocket() [4/7]

TPSocket::TPSocket ( TInetAddress  addr,
Int_t  port,
Int_t  size,
Int_t  tcpwindowsize = -1 
)

Create a parallel socket.

Connect to the specified port # at address addr. 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). Returns when connection has been accepted by remote side. Use IsValid() to check the validity of the socket. Every socket is added to the TROOT sockets list which will make sure that any open sockets are properly closed on program termination.

Create a parallel socket.

Connect to named service on the remote host. 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). Returns when connection has been accepted by remote side. Use IsValid() to check the validity of the socket. Every socket is added to the TROOT sockets list which will make sure that any open sockets are properly closed on program termination.

Definition at line 81 of file TPSocket.cxx.

◆ TPSocket() [6/7]

TPSocket::TPSocket ( const char *  host,
Int_t  port,

Create a parallel socket.

Connect to specified port # on the remote host. 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). Returns when connection has been accepted by remote side. Use IsValid() to check the validity of the socket.

◆ TPSocket() [7/7]

TPSocket::TPSocket ( const char *  host,
Int_t  port,
Int_t  size,
TSocket sock 
)

Create a parallel socket on a connection already opened via TSocket sock.

This constructor is provided to optimize TNetFile opening when instatiated via a call to TXNetFile. Returns when connection has been accepted by remote side. Use IsValid() to check the validity of the socket. Every socket is added to the TROOT sockets list which will make sure that any open sockets are properly closed on program termination.

Definition at line 180 of file TPSocket.cxx.

◆ ~TPSocket()

TPSocket::~TPSocket ( )
virtual

Cleanup the parallel socket.

Definition at line 317 of file TPSocket.cxx.

Member Function Documentation

◆ Close()

void TPSocket::Close ( Option_t option = "")
virtual

Close a parallel socket.

If option is "force", calls shutdown(id,2) to shut down the connection. This will close the connection also for the parent of this process. Also called via the dtor (without option "force", call explicitly Close("force") if this is desired).

Reimplemented from TSocket.

Definition at line 335 of file TPSocket.cxx.

inlinevirtual

Send a single message opcode.

Use kind (opcode) to set the TMessage "what" field. Returns the number of bytes that were sent (always sizeof(Int_t)) and -1 in case of error. In case the kind has been or'ed with kMESS_ACK, the call will only return after having received an acknowledgement, making the sending process synchronous.

Reimplemented from TSocket.

Definition at line 69 of file TPSocket.h.

◆ Send() [3/4]

Int_t TPSocket::Send ( Int_t  status,
Int_t  kind 
)
inlinevirtual

Send a status and a single message opcode.

Use kind (opcode) to set the TMessage "what" field. Returns the number of bytes that were sent (always 2*sizeof(Int_t)) and -1 in case of error. In case the kind has been or'ed with kMESS_ACK, the call will only return after having received an acknowledgement, making the sending process synchronous.

Reimplemented from TSocket.

Definition at line 70 of file TPSocket.h.

◆ Send() [4/4]

Int_t TPSocket::Send ( const char *  str,
Int_t  kind = kMESS_STRING 
)
inlinevirtual

Send a character string buffer.

Use kind to set the TMessage "what" field. Returns the number of bytes in the string str that were sent and -1 in case of error. In case the kind has been or'ed with kMESS_ACK, the call will only return after having received an acknowledgement, making the sending process synchronous.

Reimplemented from TSocket.

Definition at line 71 of file TPSocket.h.

◆ SendRaw()

Int_t TPSocket::SendRaw ( const void buffer,
Int_t  length,
ESendRecvOptions  opt 
)
virtual

Send a raw buffer of specified length.

Returns the number of bytes send and -1 in case of error.

Reimplemented from TSocket.

Definition at line 554 of file TPSocket.cxx.

◆ SetOption()

Int_t TPSocket::SetOption ( ESockOptions  opt,
Int_t  val 
)
virtual

Set socket options.
