Function documentation

void DoError(int level, const char* location, const char* fmt, va_list va) const
 Interface to ErrorHandler (protected).
TXSocket(const char* url, Char_t mode = 'M', Int_t psid = -1, Char_t ver = -1, const char* logbuf = 0, Int_t loglevel = -1, TXHandler* handler = 0)
 Constructor
 Open the connection to a remote XrdProofd instance and start a PROOF
 session.
 The mode 'm' indicates the role of this connection:
     'a'      Administrator; used by an XPD to contact the head XPD
     'i'      Internal; used by a TXProofServ to call back its creator
              (see XrdProofUnixConn)
     'C'      PROOF manager: open connection only (do not start a session)
     'M'      Client creating a top master
     'A'      Client attaching to top master
     'm'      Top master creating a submaster
     's'      Master creating a slave
 The buffer 'logbuf' is a null terminated string to be sent over at
 login.
TXSocket(const TXSocket& xs)
 TXSocket copy ctor.
TXSocket& operator=(const TXSocket& xs)
 TXSocket assignment operator.
~TXSocket()
 Destructor
void SetLocation(const char* loc = "")
 Set location string
void SetSessionID(Int_t id)
 Set session ID to 'id'. If id < 0, disable also the asynchronous handler.
void DisconnectSession(Int_t id, Option_t* opt = "")
 Disconnect a session. Use opt= "S" or "s" to
 shutdown remote session.
 Default is opt = "".
void Close(Option_t* opt = "")
 Close connection. Available options are (case insensitive)
   'P'   force closing of the underlying physical connection
   'S'   shutdown remote session, is any
 A session ID can be given using #...# signature, e.g. "#1#".
 Default is opt = "".
UnsolRespProcResult ProcessUnsolicitedMsg(XrdClientUnsolMsgSender* s, XrdClientMessage* msg)
 We are here if an unsolicited response comes from a logical conn
 The response comes in the form of an XrdClientMessage *, that must NOT be
 destroyed after processing. It is destroyed by the first sender.
 Remember that we are in a separate thread, since unsolicited
 responses are asynchronous by nature.
void PostMsg(Int_t type)
 Post a message of type 'type' into the read messages queue.
 This is used, for example, with kPROOF_FATAL to force the main thread
 to mark this socket as bad, avoiding race condition when a worker
 dies while in processing state.
Bool_t IsServProofd()
 Return kTRUE if the remote server is a 'proofd'
Int_t GetInterrupt(Bool_t& forward)
 Get latest interrupt level and reset it; if the interrupt has to be
 propagated to lower stages forward will be kTRUE after the call
Int_t Flush()
 Flush the asynchronous queue.
 Typically called when a kHardInterrupt is received.
 Returns number of bytes in flushed buffers.
Bool_t Create(Bool_t attach = kFALSE)
 This method sends a request for creation of (or attachment to) a remote
 server application.
Int_t SendRaw(const void* buf, Int_t len, ESendRecvOptions opt = kDontBlock)
 Send a raw buffer of specified length.
 Use opt = kDontBlock to ask xproofd to push the message into the proofsrv.
 (by default is appended to a queue waiting for a request from proofsrv).
 Returns the number of bytes sent or -1 in case of error.
Bool_t Ping(const char* ord = 0)
 Ping functionality: contact the server to check its vitality.
 If external, the server waits for a reply from the server
 Returns kTRUE if OK or kFALSE in case of error.
void RemoteTouch()
 Remote touch functionality: contact the server to proof our vitality.
 No reply from server is expected.
Int_t PickUpReady()
 Wait and pick-up next buffer from the asynchronous queue
TXSockBuf * PopUpSpare(Int_t sz)
 Pop-up a buffer of at least size bytes from the spare list
 If none is found either one is reallocated or a new one
 created
void PushBackSpare()
 Release read buffer giving back to the spare list
Int_t RecvRaw(void* buf, Int_t len, ESendRecvOptions opt = kDefault)
 Receive a raw buffer of specified length bytes.
Int_t SendInterrupt(Int_t type)
 Send urgent message (interrupt) to remote server
 Returns 0 or -1 in case of error.
Int_t Send(const TMessage &mess)
 Send a TMessage object. Returns the number of bytes in the TMessage
 that were sent and -1 in case of error.
Int_t Recv(TMessage*& mess)
 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 -5 if pipe broken (connection invalid).
 In those case mess == 0.
TObjString * SendCoordinator(Int_t kind, const char* msg = 0, Int_t int2 = 0, Long64_t l64 = 0, Int_t int3 = 0, const char* opt = 0)
 Send message to intermediate coordinator.
 If any output is due, this is returned as an obj string to be
 deleted by the caller
void SendUrgent(Int_t type, Int_t int1, Int_t int2)
 Send urgent message to counterpart; 'type' specifies the type of
 the message (see TXSocket::EUrgentMsgType), and 'int1', 'int2'
 two containers for additional information.
void InitEnvs()
 Init environment variables for XrdClient
Int_t Reconnect()
 Try reconnection after failure
Int_t GetLowSocket() const
 Auxilliary
{ return (fConn ? fConn->GetLowSocket() : -1); }
Int_t GetClientID() const
{ return -1; }
Int_t GetClientIDSize() const

void RemoveClientID()
{ }
void SetClientID(Int_t )

void SetSendOpt(ESendRecvOptions o)
{ fSendOpt = o; }
Int_t Send(const TMessage &mess)
 Send interfaces
Int_t Send(Int_t kind)
{ return TSocket::Send(kind); }
Int_t Send(Int_t status, Int_t kind)
{ return TSocket::Send(status, kind); }
Int_t Recv(TMessage*& mess)
 Recv interfaces
Int_t Recv(Int_t &status, Int_t &kind)
{ return TSocket::Recv(status, kind); }
Int_t Recv(char *mess, Int_t max)
{ return TSocket::Recv(mess, max); }
void SetInterrupt()
 Interrupt the low level socket
Int_t SetOption(ESockOptions , Int_t )
 Standard options cannot be set
{ return 0; }
void DisableTimeout()
 Disable / Enable read timeout
{ fDontTimeout = kTRUE; }
