The function *general_work* is the place where a block processes input
items and generates output items according to its functionality (such as
filter). Besides the functionality, you have to tell the invoker how many
items from each input port are consumed by invoking function *consume* or
*consume_each* and how many items for each output port are generated
through return value.

Exactly, *general_work* are all automatically invoked by gr-scheduler, one
of the core component of gnuradio, which handles runtime stuff of whole
flow graphs. So, you don't have to control the execution of general_work().
The following PDF gives a brief introduction about gr-scheduler, including
*general_work* function:
