    _sl_HandleAsync_DnsGetHostByService

    CALLER          NWP - Async event on sl_DnsGetHostByService with IPv4 Family


    DESCRIPTION:

                    Async event on sl_DnsGetHostByService command with IPv4 Family.
                    Return service attributes like IP address, port and text according to service name.
                    The user sets a service name Full/Part (see example below), and should get the:
                    1. IP of the service
                    2. The port of service.
                    3. The text of service.

                    Hence it can make a connection to the specific service and use it.
                    It is similar to get host by name method.

                    It is done by a single shot query with PTR type on the service name.



                    Note:
                    1. The return's attributes are belonged to first service that is found.
                    It can be other services with the same service name will response to
                    the query. The results of these responses are saved in the peer cache of the NWP, and
                    should be read by another API.


        PARAMETERS:

                  pVoidBuf - is point to opcode of the event.
                  it contains the outputs that are given to the user

                  outputs description:

                   1.out_pAddr[]                    - output: Contain the IP address of the service.
                   2.out_pPort                      - output: Contain the port of the service.
                   3.inout_TextLen                  - Input:  Contain the max length of the text that the user wants to get.
                                                              it means that if the test of service is bigger that its value than
                                                              the text is cut to inout_TextLen value.
                                                      Output: Contain the length of the text that is returned. Can be full text or part
                                                              of the text (see above).

                   4.out_pText                      - Contain the text of the service (full or part see above- inout_TextLen description).
