[Qt-interest] Too many files open error on Mac OS

[paulf at free.fr]

Hi

Are you sure that your application does not have a resource leak of opened files? If so, then simply increasing the resource limit isn't a good solution.

Tools like Purify can detect leaked open file resources.

Subject: [Qt-interest] Too many files open error on Mac OS

Hello,

My QT 4.5 GUI program opens a lot of files. On windows it is working 
fine, but on Mac OS it receives error - too many files open.

If i type in bash:

ulimit -n
256

I found out how to fix it:

echo limit maxfiles 2048 1000000 > /etc/launchd.conf
#reboot
ulimit -n
2048

I deliver program to users in dmg archive.
They just mount it and launch program.
It can be a problem for some of them to make such a tuning in bash.

Can program itself increase number of files, it can open, without need 
to reboot?

Thanks
