Your client can look up your server-registered properties by sending GET_PROP messages to the server. Your server will (asynchronously) return the property's value in a return GET_PROP message.
The format for a client-originating GET_PROP message is:
GET_PROP property
where
| property | is a PLAIN envelop whose data field names the property. |
The format for a server-originating GET_PROP message is:
GET_PROP (property|property_and_value)
where
property
| is an envelop containing only the property name. |
|
property_and_value
| is an envelop containing both the property and its value. |
|
The contents of the property_and_value's data field is formatted as follows:
property=value
where, of course, property is the name of the property and value is its value. The manner in which the value is represented depends on the property, and is defined individually for each property. It may be text or binary.
If the property is not registered with the server, then the envelop will contain only the property name, but not the equals delimeter or value.
