I wrote the below code

    _NO_DEFAULT.check(regtype)
    @_DNSServiceBrowseReply
    def _callback(sdRef, flags, interfaceIndex, errorCode, serviceName, regtype, replyDomain, context):
        if (callBack is not None):
            callBack(sdRef, flags, interfaceIndex, errorCode, serviceName.decode(), regtype.decode(), replyDomain.decode())
    _global_lock.acquire()
    try:
        sdRef = _DNSServiceBrowse(flags, interfaceIndex, regtype, domain, _callback, None)
    finally:
        _global_lock.release()
    sdRef._add_callback(_callback)
    return sdRef

What's a good function header?

#Here's a good function header.

def DNSServiceBrowse(flags=0, interfaceIndex=kDNSServiceInterfaceIndexAny, regtype=_NO_DEFAULT, domain=None, callBack=None):
