* The basic flow of operations for the process_* routines
* is as follows :
*
* Create and Initialize the request message.
* Set the header information in the request message.
* Send the request message to the server
* Free the request message
* Receive the response message from the server.
* Retrieve header information from the response message.
* Retrieve message body from the response message.
* Free the response message
*
* In all the process_* routines, the following variables
* are used.
*
* req_msg => The RTSP Request Message
* rsp_msg => The RTSP Response Message
* err => error number returned by RTSP APIs
