Detailed Description

This class is designed to help users minimize their effort of packing and unpacking numerical values every time they need to send one.

All methods provided in this class will pack values before writing them to the network. Again, all methods available in this class will unpack all values gotten from the network before returning them to the users. This class is derived from QUANTAnet_tcp_c class and thus, compatible with the class. So it is possible to use QUANTAnet_extendedTcpClient_c in a machine and use QUANTAnet_tcp_c class in the other, or vice versa; you are just losing the convenience of using simple methods provided in this class in return and you have to pack and unpack by yourself. If you want to use this class in the server side, make sure to create an instance of QUANTAnet_extendedTcpServer_c class instead of QUANTAnet_tcpServer_c since QUANTAnet_extendedTcpServer_c gives you access to all methods available in this client class.

int QUANTAnet_tcpClient_c::connectToServer (  const char *  ip, int  port )  [inherited]

Connect to a server. Returns: A negative number(that is returned by a socket sonnect() call if failed. Else returns client's socket file descriptor. (note: the return value in the previous versions was a zero in case of an error - this has been changed to a negative value from version 1.2)

void QUANTAnet_tcpClient_c::getRemoteIP (  char *  name  )  [inherited]

Get the IP address of remote connection. If you are a client this returns the ip of the destination server. If you are a server this returns the ip of the destination client.

unsigned int QUANTAnet_tcpClient_c::getRemoteIP (   )  [inherited]

Get the IP address of remote connection. If you are a client this returns the ip of the destination server. If you are a server this returns the ip of the destination client.

int QUANTAnet_tcpClient_c::initSendStats (  const char *  monitorClientIP, int  port = PERF_DAEMON_DEFAULT_PORT )  [inherited]

Initialize sendStats - provide the IP of the perfDaemon and an optional port number to connect to. This should be done initially before using the sendStats API. Parameters: monitorClientIP  IP address of the perfDameon to connect to port  Port number at which the perfDaemon is running -this is optional. The default port number for perfDaemon is 9500 -so a different port number has to be specified if the perfDaemon is running ona different port. Returns: Either QUANTAnet_perfMonitor_c::OK or QUANTAnet_perfMonitor_c::FAILED

int QUANTAnet_tcpClient_c::isReady (   )  [inherited]

Determines if a socket is ready to write or read or both. Returns: Either: QUANTAnet_tcpClient_c::NOT_READY or QUANTAnet_tcpClient_c::READY_TO_WRITE or QUANTAnet_tcpClient_c::READY_TO_READ or QUANTAnet_tcpClient_c::READY_TO_READ_AND_WRITE

int QUANTAnet_tcpClient_c::isReadyToRead (   )  [inherited]

Determines if a socket has data available to read. Returns: Either: QUANTAnet_tcpClient_c::NOT_READY or QUANTAnet_tcpClient_c::READY_TO_READ

int QUANTAnet_tcpClient_c::isReadyToWrite (   )  [inherited]

Determines if a socket is ready to write. Returns: Either: QUANTAnet_tcpClient_c::NOT_READY or QUANTAnet_tcpClient_c::READY_TO_WRITE

int QUANTAnet_tcpClient_c::logStats (  char *  streamInfo, char *  comment, FILE *  filePtr )  [inherited]

This logs performance statistics in a file. The user opens a file and passes the file pointer with this function and results of monitoring are written into the logfile. Parameters: streamInfo  A label describing the stream that is being monitored. comment  A comment on the event that marks the time at which the stream is being monitored filePtr  File pointer to the file in which the results of monitoring are to be stored Returns: Either QUANTAnet_perfMonitor_c::OK or QUANTAnet_perfMonitor_c::FAILED

int QUANTAnet_tcpClient_c::read (  char *  ptr, int *  nbytes, int  blockingType )  [inherited]

Parameters: nbytes  Fill nbytes with num bytes you want to read. nbytes will return with number of bytes successfully read. blockingtype  BLOCKING means that it will block waiting for data or until the timeout period expires. Change the timeout period by calling setTimeOut(). NON_BLOCKING means that if there is no data to be read this call will return immediately. If it does get some data it will keep reading until the specified number of bytes is received, or if it timesout, or if the connection is broken. In the latter two cases the number of bytes it was able to read is returned. In either the BLOCKING or NON_BLOCKING case you can set the time out period to never time out by setting the timeout time to: NO_TIME_OUT. Returns: SOCKET_NOT_OPEN, NON_BLOCKING_HAS_NO_DATA, TIMED_OUT, CONNECTION_TERMINATED, OK, errno

writes a number of integer values Parameters: intArray  integer values that will be sent to the network stream size  the number of integers you want to send blockingType  either QUANTAnet_tcpClient_c::BLOCKING for blocking operation or QUANTAnet_tcpClient_c::NON_BLOCKING for non-blocking operation

int QUANTAnet_extendedTcpClient_c::writeLong (  long  value, int  blockingType )

writes a long integer value Parameters: value  long integer value that is going to be written to the network stream blockingType  either QUANTAnet_tcpClient_c::BLOCKING for blocking operation or QUANTAnet_tcpClient_c::NON_BLOCKING for non-blocking operation

int QUANTAnet_extendedTcpClient_c::writeLongArray (  long *  longArray, int  size, int  blockingType )

writes a number of long integer values Parameters: longArray  long integer values that will be sent to the network stream size  the number of long integers you want to send blockingType  either QUANTAnet_tcpClient_c::BLOCKING for blocking operation or QUANTAnet_tcpClient_c::NON_BLOCKING for non-blocking operation

int QUANTAnet_tcpClient_c::writev (  QUANTAnet_iovec_c  q_iovec, int  blockingType )  [inherited]

Parameters: q_iovec  QUANTAnet_iovec_c blockingtype  QUANTAnet_tcpClient_c::BLOCKING or, NON_BLOCKING Returns: 1 if succed, or errno if fails comment:writev gives invalid argument error when iovec length is not initialized.
