Re: [Quickfix-developers] Integrate socket connections intoapplication-wideasync socket loop

[Mark T. K. <mke...@di...>]

i wanted to do something similar with perl on linux but i found it
easier to use the quickfix callbacks to convert each received message
into a string which i write to myself via a pipe.  that trivially
integrates with a select/poll-based event loop.  its not efficient
in an absolute sense (because of the overhead of marshalling and
demarshaling the message an extra time) but it took no time to
code.  and with today's processors, the overhead is lost in the noise.
