CFNetServiceGetTXTData(_:)

Declaration

func CFNetServiceGetTXTData(_ theService: CFNetService) -> Unmanaged<CFData>?

Parameters

• theService:

  Reference for the network service whose TXT record data is to be obtained; cannot be NULL. Note that in order to get TXT record data, you must resolve theService by calling Cfnetserviceresolve or Cfnetserviceresolvewithtimeout(_:_:_:) before calling this function.

Return Value

CFDataRef object containing the requested TXT data and suitable for passing to CFNetServiceCreateDictionaryWithTXTData(_:_:), or NULL if the service’s TXT data has not been resolved.

Discussion

This function gets the data from the service’s TXT records.

Special Considerations

This function gets the data in a thread-safe way, but the data itself is not safe if the service is altered from another thread.
