RES: How to use PQconsumeInput and PQisBusy correctly ?

This is only a sample to demonstrante that I want. But I have plans to do
something, in fact, it will be a win32 application , that shows a non modal
Dialog with a Cancel button and a progessbar. If user wanna cancel the
query, just press cancel button. So, I don't want allows the user to do
anything else, they can't navigate trough a program, because this will
generate another query to be submited to pg, and I don't have plans to
create another one connection for this user. So, they will wait for query to
be finish or then press cancel, that is it.

But, my question, I always should call pqconsume before a pqisbusy ? Can I
use it in a loop ? It will cause some kind of traffic ?
