* Throughout, change fhandler_*::read and fhandler_*::raw_read to void functionsChristopher Faylor2002-12-141-1/+1
| | | | | | | | | | | whose second arguments are both the lenght and the return value. * fhandler.cc (fhandler_base::read): Rework slightly to use second argument as input/output. Tweak CRLF stuff. (fhandler_base::readv): Accommodate fhandler_*::read changes. * cygthread.h (cygthread::detach): Declare as taking optional handle argument. (cygthread::detach): When given a handle argument, wait for the handle to be signalled before waiting for thread to detach. Return true when signal detected.
