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.

Waits for this socket to change status.
If interest=kRead, the socket will be watched to see if characters become available for reading; if interest=kWrite the socket will be watched to see if a write will not block. The argument 'timeout' specifies a maximum time to wait in millisec. Default no timeout. Returns 1 if a change of status of interest has been detected within timeout; 0 in case of timeout; < 0 if an error occured.

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
Reimplemented in TXSocket, TPSocket, TServerSocket, and TSSLSocket.

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.

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.

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.

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 in TServerSocket.

Check if TProcessIDs must be sent.
The list of TProcessIDs in the object in the message is found by looking in the TMessage bits. We send only the TProcessIDs not yet send on this socket.

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).

Check if TStreamerInfo must be sent.
The list of TStreamerInfo of classes in the object in the message is in the fInfos list of the message. We send only the TStreamerInfos not yet sent on this socket.

See comments for function SetCompressionSettings.
Definition at line 1065 of file TSocket.cxx.
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.
