sl_NetAppMDNSRegisterService
CALLER user from its host
DESCRIPTION:
Add/delete service
The function manipulates the command that register the service and call
to the NWP in order to add/delete the service to/from the mDNS package and to/from the DB.
This register service is a service offered by the application.
This unregister service is a service offered by the application before.
The service name should be full service name according to RFC
of the DNS-SD - means the value in name field in SRV answer.
Example for service name:
1. PC1._ipp._tcp.local
2. PC2_server._ftp._tcp.local
If the option is_unique is set, mDNS probes the service name to make sure
it is unique before starting to announce the service on the network.
Instance is the instance portion of the service name.
PARAMETERS:
The command is from constant parameters and variables parameters.
Constant parameters are:
ServiceLen - The length of the service.
TextLen - The length of the service should be smaller than 64.
port - The port on this target host.
TTL - The TTL of the service
Options - bitwise parameters:
bit 0 - is unique (means if the service needs to be unique)
bit 31 - for internal use if the service should be added or deleted (set means ADD).
bit 1-30 for future.
The variables parameters are:
Service name(full service name) - The service name.
Example for service name:
1. PC1._ipp._tcp.local
2. PC2_server._ftp._tcp.local
Text - The description of the service.
should be as mentioned in the RFC
(according to type of the service IPP,FTP...)
NOTE - pay attention
1. Temporary - there is an allocation on stack of internal buffer.
Its size is NETAPP_MDNS_MAX_SERVICE_NAME_AND_TEXT_LENGTH.
It means that the sum of the text length and service name length cannot be bigger than
NETAPP_MDNS_MAX_SERVICE_NAME_AND_TEXT_LENGTH.
If it is - An error is returned.
2. According to now from certain constraints the variables parameters are set in the
attribute part (contain constant parameters)
RETURNS: Status - the immediate response of the command status.
0 means success.

_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).
