Hi all,
I finally could find the options I needed for valgrind to behave as I wanted.
I redirected valgrind's input and output to another console as follows:
valgrind --input-fd=3 --log-fd=4 myapp 3</dev/tty2 4>/dev/tty2
And now, valgind does what I need and let's my app work correctly with its own
input and output.
Have a nice day. ChD

Subject: Problem using valgrind
Hi all,
I noticed a strange instability in one of my apps running on a Fedora 9 box.
Since the app's behaviour let me suspect a memory corruption problem, I'm
running it through valgrind to track the bug down.
However, the app links with OpenSSL, a library which is known not to run fairly
in valgrind. This can be worked around by launching valgrind with
--gen-suppressions and this is what I did.
Problem: My app also needs sometimes to read from stdin and when it does, it
always take precedence over valgrind. How can I change this behaviour please?
i.e. I'd like to manage the input such as valgrind takes it in priority when it
needs some and the app takes it if and only if valgrind doesn't need it.
Many thanks in advance for any advice. Have a nice day. ChD
