Guys,
I am using quickfix on FreeBSD 8.1 and saw an issue where the select()
system call on a socket that has
been closed with close() before does not return with a value < 0. This
happens, whenever a thread context
switch happens between the close() and select().
This is probably a bug in FreeBSD and I will address that in the
appropriate mailing list.
Nevertheless I have written and attached a small patch for quickfix that
fixes this behaviour as I am not
sure if one can rely on the return value of select() for all OS'es.
Cheers,
Heri
