I have a need for this now. I have a client that sends an inquire
command to the server, but the data needs to be sent ASSUAN_LINELENGTH
bytes at a time (memory restrictions). assuan_transact() can't do this
with it's inquire callback and keep parsing status messages from the
server at the same time, which I also need. I can't call
assuan_read_line() to do the status line parsing in the inquire callback
because assuan_read_line() blocks?

I'm guessing how the asynchronous client works: If I were to call
assuan_transact() which would setup the callbacks, then call
assuan_process_next() until the inquire callback returns EOF, or an
error, to finish the command. Then call assuan_process_done() to get the
command result from the server. Is this right?
