Description

Communication on a PlumaMessageBus is done through messages. Messages are sent over the bus and received by connecting callbacks on the message bus. A PlumaMessage is an instantiation of a PlumaMessageType, containing values for the arguments as specified in the message type.

A message can be seen as a method call, or signal emission depending on who is the sender and who is the receiver. There is no explicit distinction between methods and signals.

Functions

void
pluma_message_get (PlumaMessage *message,
                   ...);

Get values of message arguments. The supplied var_args should contain pairs of keys and pointers to variables which are set to the argument value for the specified key.
