Hi Siva,

yes, referring to the introductory tutorials I can explain:

gr::block, the mother of all blocks that can process samples, has
general_work. That gets called to process samples, but does not make
any guarantees about the ratio of the numbers of input- and output
items, so you need to call consume() yourself to tell GNU Radio how
many input items you consumed to produce your output.

work is the function of a block that has a defined ratio between the
numbers of in- and output items (gr::sync_block and derived types,
which itself is a subclass of gr::block),
which "wraps" the functionality to alleviate the need to call
consume() yourself, since from the number of items a sync block
produced you directly know how many it consumed.

So, no, by choice of design we can't have the same behaviour with a
single method.

Hope that was helpful!

Greetings,
Marcus
