If you mean synchronous manner, then the answer is no.  A blocking API
would block the event loop and Emacs would appear to be "frozen".

You can however use a process-filter.  That's a function that is called
with the data received from the other end.  So you always know when data is
ready to process.

If you must use a synchronous mode (e.g. for the the completion code)
then you could use accept-process-output and/or recursive-edit but I
would avoid that as long as possible.
