# 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
