const char *  service,
Int_t  tcpwindowsize = -1 
)
TSocket::TSocket ( TInetAddress  addr,
Int_t  port,
Int_t  tcpwindowsize = -1 
)

Create a 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.

TSocket::TSocket ( const char *  host,
const char *  service,
Int_t  tcpwindowsize = -1 
)

Create a 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.

TSocket::TSocket ( const char *  url,
Int_t  port,
Int_t  tcpwindowsize = -1 
)

Create a socket; see CreateAuthSocket for the form of url.

Connect to the specified port # on the remote host. If user is specified in url, try authentication as user. 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 216 of file TSocket.cxx.

TSocket::TSocket ( const char *  sockpath)

Create a socket in the Unix domain on 'sockpath'.

Returns when connection has been accepted by the server. 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 261 of file TSocket.cxx.

TSocket::TSocket ( Int_t  desc)

Create a socket.

The socket will adopt previously opened TCP socket with descriptor desc.

Definition at line 294 of file TSocket.cxx.

TSocket::TSocket ( Int_t  desc,

Create a socket.

The socket will adopt previously opened Unix socket with descriptor desc. The sockpath arg is for info purposes only. Use this method to adopt e.g. a socket created via socketpair().

Bool_t TSocket::Authenticate ( const char *  user)
protected

Authenticated the socket with specified user.

Referenced by CreateAuthSocket(), and TPSocket::TPSocket().

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

Close the 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).

)
static

Creates a socket or a parallel socket and authenticates to the remote server specified in 'url' on remote 'port' as 'user'.

url: [[proto][p][auth]://]host[/?options]

where proto = "sockd", "rootd", "proofd" indicates the type of remote server if missing "sockd" is assumed ("sockd" indicates any remote server session using TServerSocket) [p] = for parallel sockets (forced internally for rootd) [auth] = "up", "s", "k", "g", "h", "ug" to force UsrPwd, SRP, Krb5, Globus, SSH or UidGid authentication [options] = "m" or "s", when proto=proofd indicates whether we are master or slave (used internally by TSlave)

An already opened connection can be used by passing its socket in opensock.

If 'err' is defined, '*err' on return from a failed call contains an error code (see NetErrors.h).

Example:

TSocket::CreateAuthSocket("qwerty","rootdps://machine.fq.dn",5051)

creates an authenticated socket to a rootd server running on remote machine machine.fq.dn on port 5051; "parallel" sockets are forced internally because rootd expects parallel sockets; however a simple socket will be created in this case because the size is 0 (the default); authentication will attempt protocol SRP first.

TSocket::CreateAuthSocket("qwerty","pk://machine.fq.dn:5052",3)

creates an authenticated parallel socket of size 3 to a sockd server running on remote machine machine.fq.dn on port 5052; authentication will attempt protocol Kerberos first.

NB: may hang if the remote server is not of the correct type; at present TSocket has no way to find out the type of the remote server automatically

Returns pointer to an authenticated socket or 0 if creation or authentication is unsuccessful.

Creates a socket or a parallel socket and authenticates to the remote server.

url: [[proto][p][auth]://][user@]host[:port][/service][?options]

where proto = "sockd", "rootd", "proofd" indicates the type of remote server; if missing "sockd" is assumed ("sockd" indicates any remote server session using TServerSocket) [p] = for parallel sockets (forced internally for rootd; ignored for proofd) [auth] = "up", "s", "k", "g", "h", "ug" to force UsrPwd, SRP, Krb5, Globus, SSH or UidGid authentication [port] = is the remote port number [service] = service name used to determine the port (for backward compatibility, specification of port as priority) options = "m" or "s", when proto=proofd indicates whether we are master or slave (used internally by TSlave)

An already opened connection can be used by passing its socket in opensock.

If 'err' is defined, '*err' on return from a failed call contains an error code (see NetErrors.h).

Example:

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).

void TSocket::SetCompressionSettings ( Int_t  settings = 1)

Used to specify the compression level and algorithm: settings = 100 * algorithm + level.

level = 0, objects written to this file will not be compressed. level = 1, minimal compression level but fast. .... level = 9, maximal compression level but slower and might use more memory. (For the currently supported algorithms, the maximum level is 9) If compress is negative it indicates the compression level is not set yet.

The enumeration ROOT::ECompressionAlgorithm associates each algorithm with a number. There is a utility function to help to set the value of the argument. For example, ROOT::CompressionSettings(ROOT::kLZMA, 1) will build an integer which will set the compression to use the LZMA algorithm and compression level 1. These are defined in the header file Compression.h.

Note that the compression settings may be changed at any time. The new compression settings will only apply to branches created or attached after the setting is changed and other objects written after the setting is changed.
