Getting most recent message from queue

[Jan Banan]

 Hallo 

are there in D-BUS any simple mechanism for obtaining the most recent
message of specified type (filter) from receiver`s queue ?

Example: [Most recent]  ->XAXXXAXXAXA-> [oldest] -> receiver APP 

I`d like to pop message type 'A' but the most recent  and all other
message type 'A' discard. Message type 'X' should stay untouched. Is it
this possible to do ? I`d like to use only exported low-level C API and
signal type messages. 

               Best Jan
