CVSROOT:	/cvs/uberbaum
Module name:	winsup
Changes by:	cgf@sourceware.org	2011-05-31 00:26:37

Modified files:
	cygwin         : ChangeLog dtable.cc fhandler.cc fhandler.h 
	                 pipe.cc 

Log message:
	* dtable.cc (dtable::select_write): Add missing argument to debug_printf.
	* fhandler.cc (fhandler_base_overlapped::setup_overlapped): Explicitly set
	io_pending to false.
	(fhandler_base_overlapped::has_ongoing_io): Call GetOverlappedResult to force
	completion of I/O.
	(fhandler_base_overlapped::wait_overlapped): Rewrite to correctly deal with
	nonblocking reads and to make more race proof.
	(fhandler_base_overlapped::raw_write): Deal with new enum values.
	(fhandler_base_overlapped::raw_read): Ditto.  Don't deal with ongoing I/O here
	since it makes no sense in the read context.
	* fhandler.h (enum wait_return): Add overlapped_unknown,
	overlapped_nonblocking_no_data.
	* pipe.cc (pipe): Add debugging output.
