TServerSocket::TServerSocket	(	Int_t	port,

		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.

Member Function Documentation

◆ Accept()

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().

Reimplemented in TPServerSocket.

Definition at line 204 of file TServerSocket.cxx.

◆ Authenticate()

Bool_t TServerSocket::Authenticate ( TSocket * sock )

private

Check authentication request from the client on new open connection.

UChar_t TServerSocket::GetAcceptOptions ( )

static

Return default options for Accept.

Definition at line 272 of file TServerSocket.cxx.

◆ GetLocalInetAddress()

TInetAddress TServerSocket::GetLocalInetAddress ( )

virtual

Return internet address of host to which the server socket is bound, i.e.

the local host. In case of error TInetAddress::IsValid() returns kFALSE.

Reimplemented from TSocket.

Definition at line 245 of file TServerSocket.cxx.

◆ GetLocalPort()

◆ Recv() [1/4]

Int_t TServerSocket::Recv	(	char *	str,
		Int_t	max
	)

inlinevirtual

Receive a character string message of maximum max length.

The expected message must be of type kMESS_STRING. Returns length of received string (can be 0 if otherside 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).

Reimplemented from TSocket.

◆ Recv() [2/4]

Int_t TServerSocket::Recv	(	char *	str,

inlinevirtual

Receive a character string message of maximum max length.

Returns in kind the message type. Returns length of received string+4 (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).

Reimplemented from TSocket.

Definition at line 86 of file TServerSocket.h.

◆ Recv() [3/4]

Int_t TServerSocket::Recv	(	Int_t &	status,
		Int_t &	kind

inlinevirtual

Receives a status and a message type.

Returns length of received integers, 2*sizeof(Int_t) (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).

Reimplemented from TSocket.

Definition at line 82 of file TServerSocket.h.

◆ Recv() [4/4]

Int_t TServerSocket::Recv ( TMessage *& mess )

inlinevirtual

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). In those case mess == 0.

◆ RecvRaw()

Int_t TServerSocket::RecvRaw	(	void *	buffer,
		Int_t	length,
		ESendRecvOptions	opt = `kDefault`
	)

inlinevirtual

Receive a raw buffer of specified length bytes.

Using option kPeek one can peek at incoming data. Returns number of received bytes. Returns -1 in case of error. In case of opt == kOob: -2 means EWOULDBLOCK and -3 EINVAL. In case of non-blocking mode (kNoBlock) -4 means EWOULDBLOCK. Returns -5 if pipe broken or reset by peer (EPIPE || ECONNRESET).

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 74 of file TServerSocket.h.

◆ Send() [2/4]

Int_t TServerSocket::Send ( const TMessage & mess )

inlinevirtual

Send a TMessage object.

Returns the number of bytes in the TMessage that were sent and -1 in case of error. In case the TMessage::What has been or'ed with kMESS_ACK, the call will only return after having received an acknowledgement, making the sending process synchronous. Returns -4 in case of kNoBlock and errno == EWOULDBLOCK. Returns -5 if pipe broken or reset by peer (EPIPE || ECONNRESET). support for streaming TStreamerInfo added by Rene Brun May 2008 support for streaming TProcessID added by Rene Brun June 2008

◆ Send() [3/4]

Int_t TServerSocket::Send ( Int_t kind )

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.

◆ Send() [4/4]

Int_t TServerSocket::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 72 of file TServerSocket.h.

◆ SendObject()

Int_t TServerSocket::SendObject	(	const TObject *	obj,
		Int_t	kind = `kMESS_OBJECT`
	)

inlinevirtual

Send an object.

Returns the number of bytes 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 synchronous.

Reimplemented from TSocket.

Definition at line 76 of file TServerSocket.h.

◆ SendRaw()

Int_t TServerSocket::SendRaw	(	const void *	buffer,
		Int_t	length,
		ESendRecvOptions	opt = `kDefault`
	)

inlinevirtual

Send a raw buffer of specified length.

Using option kOob one can send OOB data. Returns the number of bytes sent or -1 in case of error. Returns -4 in case of kNoBlock and errno == EWOULDBLOCK. Returns -5 if pipe broken or reset by peer (EPIPE || ECONNRESET).

Reimplemented from TSocket.

Definition at line 78 of file TServerSocket.h.

void TServerSocket::SetAcceptOptions ( UChar_t mod )

static

Use: kSrvAuth require client authentication kSrvNoAuth do not require client authentication

Definition at line 283 of file TServerSocket.cxx.

◆ ShowAcceptOptions()

void TServerSocket::ShowAcceptOptions ( )

static

Print default options for Accept.

Definition at line 291 of file TServerSocket.cxx.
