#  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 janovetz@tempest.ece.uiuc.edu Sat Mar  6 10:34:11 1999
Date: Thu, 4 Mar 1999 19:37:37 -0600
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
