// .SECTION Description
// This abstract class encapsulates a BSD socket. It provides an API for
// basic socket operations.

// Description:
// Check is the socket is alive.

// ------ Communication API ---
// Description:
// These methods send data over the socket.
// Returns 1 on success, 0 on error and raises vtkCommand::ErrorEvent.

// Description:
// Receive data from the socket.
// This call blocks until some data is read from the socket.
// When readFully is set, this call will block until all the
// requested data is read from the socket.
// 0 on error, else number of bytes read is returned. On error,
// vtkCommand::ErrorEvent is raised.

// GetConnected() returns true.

// Selects set of sockets. Returns 0 on timeout, -1 on error.
