<!-- ##### STRUCT LmConnection ##### -->

<para>

This should not be accessed directly. Use the accessor functions as described below.

</para>

<!-- ##### ENUM LmHandlerResult ##### -->

<para>

The return type of an LmMessageHandler. This determines whether more message handlers should be called.

</para>

@LM_HANDLER_RESULT_REMOVE_MESSAGE: Stop calling message handlers. The message handler returning this declares the message has been handled and should be removed.

@LM_HANDLER_RESULT_ALLOW_MORE_HANDLERS: Return to continue the calling handlers from the handler list. This declares that another handlers should handle the message.

<!-- ##### ENUM LmHandlerPriority ##### -->

<para>

Since the handlers decide whether to stop the calling chain with there return values it's sometimes decirable to be able to set priority. For example a handler that only logs all incoming messages and then pass the message on to another handler wants to have priority %LM_HANDLER_PRIORITY_FIRST. An handler that should take all messages that wasn't handled by anything else would want to have priority %LM_HANDLER_PRIORITY_LAST. If several handlers have the same priority nothing can be said about the order the handlers will be called in.

</para>

@LM_HANDLER_PRIORITY_LAST: Call the handler after all handlers with #NORMAL and #FIRST priority.

@LM_HANDLER_PRIORITY_NORMAL: Called before handlers with priority #LAST and after those with #FIRST.

@LM_HANDLER_PRIORITY_FIRST: These are called before all other handlers.

<!-- ##### ENUM LmDisconnectReason ##### -->

<para>

@LM_DISCONNECT_REASON_PING_TIME_OUT: Connection to the server timed out.

@LM_DISCONNECT_REASON_HUP: The socket emitted that the connection was hung up.

@LM_DISCONNECT_REASON_ERROR: A generic error somewhere in the transport layer.

@LM_DISCONNECT_REASON_UNKNOWN: An unknown error.

<!-- ##### ENUM LmConnectionState ##### -->

<para>

</para>

@LM_CONNECTION_STATE_CLOSED: The connection is closed.
