+#  README for fdopen() test

+
+Resolution: Fixed
+
+This test failed because fcntl() did not yet support the F_GETFL
+control operation.  This code was added (along with F_SETFL) and
+the test began to work.
+
+-----------------------
+
+This is the original email that the test came from:

+From: Jake Janovetz <janovetz@tempest.ece.uiuc.edu>
+To: rtems-snapshots@oarcorp.com
+Subject: More on fdopen()
+
+Hello all...
+
+Sorry to beat a dead horse (to me, it's still living), but I
+still can't get the fdopen stuff to work...  Since I cannot
+find a reference to fdopen() under the rtems source tree,
+I presume its only incarnation in 'newlib'.  The
+newlib-1.8.1 19990302 patch does not seem to have a reference
+to fdopen, so I don't see anything modified there.
+
+I'd like to know where the fdopen fix resides, so I know I 
+have it.
+
+Finally, I'm including a simple test for fdopen().  If some
+merciful soul can run this (Eric has already verified that his
+version works -- I'm hoping that maybe a patch didn't make it
+into 0302), I would appreciate it.
+
+    Cheers,
+    Jake
