/* For this simple training app, only a single channel/connection is used for the entire life of this app. */
/* This example uses Unix I/O contents and basic TCP/IP like file descriptor and socket.*/
/* This example suite uses write descriptor in our client/consumer type examples in mainly 2 areas with
* the I/O notification mechanism being used:
* Details of those functions could be found in API development guide.
* 1) rsslInitChannel() function which exchanges various messages to perform necessary UPA transport
* negotiations and handshakes to complete channel initialization.
* 2) rsslFlush() calls used throughout the application (after module 1a), together with rsslWrite() calls, such
* as in sendMessage() function. The write descriptor can be used to indicate when the socketId has write
* availability and help with determining when the network is able to accept additional bytes for writing.
*
* For the RsslChannel initialization process, if using I/O, a client/consumer application should register the
* RsslChannel.socketId with the read, write, and exception file descriptor sets. When the write descriptor
* alerts the user that the socketId is ready for writing, rsslInitChannel is called (this sends the
* initial connection handshake message). When the read file descriptor alerts the user that the socketId
* has data to read, rsslInitChannel is called - this typically reads the next portion of the handshake.
* This process would continue until the connection is active.
*
* Typically, calls to rsslInitChannel are driven by I/O on the connection, however this can also be
* accomplished by using a timer to periodically call the function or looping on a call until the channel
* transitions to active or a failure occurs. Other than any overhead associated with the function call,
* there is no harm in calling rsslInitChannel more frequently than required. If no work is required at
* the current time, the function will return and indicate that connection is still in progress.
*/
/* This example suite also uses a clean FD sets and a dirty FD sets for I/O notification.
* select() - a system call for examining the status of file_descriptors.
* Tells us that there is data to read on the FDs.
* Since select() modifies its file descriptor sets, if the call is being used in a loop, then the fd sets must
* be reinitialized before each call. Since they act as input/output parameters for the select() system call;
* they are read by and modified by the system call. When select() returns, the values have all been modified
* to reflect the set of file descriptors ready. So, every time before you call select(), you have to
* (re)initialize the fd_set values. Here we maintain 2 sets FD sets:
* a) clean FD sets so that we can repeatedly call select call
* b) dirty FD sets used in the actual select call (I/O notification mechanism)
* Typically, you reset the dirty FD sets to be equal to the clean FD sets before you call select().
