dbus-check-event is a compiled Lisp function in `
Checks whether EVENT is a well formed D-Bus event.
EVENT is a list which starts with symbol `dbus-event':
(dbus-event BUS TYPE SERIAL SERVICE PATH INTERFACE MEMBER HANDLER &rest ARGS)
BUS identifies the D-Bus the message is coming from. It is
either a Lisp symbol, `:system' or `:session', or a string
denoting the bus address. TYPE is the D-Bus message type which
has caused the event, SERIAL is the serial number of the received
D-Bus message. SERVICE and PATH are the unique name and the
object path of the D-Bus object emitting the message. INTERFACE
and MEMBER denote the message which has been sent. HANDLER is
the function which has been registered for this message. ARGS
are the arguments passed to HANDLER, when it is called during
event handling in `dbus-handle-event'.
This function raises a `dbus-error' signal in case the event is
not well formed.
