public ul_bool ULCreateNotificationQueue(
    SQLCA * sqlca,
    char const * name,
    char const * parameters
)

True on success; otherwise, returns false.

Queue names are scoped per-connection, so different connections can create queues with the same name. When an event notification is sent, all queues in the database with a matching name receive (a separate instance of) the notification. Names are case insensitive. A default queue is created on demand for each connection when calling the ULRegisterForEvent method if no queue is specified. This call fails with an error if the name already exists or isn't valid.
