Once you've determined to the best of your abilities that the problem isn't some misunderstanding of the function call or utility you're using, or a mere typo, you may enter the realm of the QNX technical support department. This is nothing to be afraid of—most customers are extremely pleased with the level of technical support they get from QNX Software Systems.
There are two ways of contacting the QNX technical support group: by phone or via the web. The QNX website (at http://www.qnx.com), has a Community area called Foundry27, at http://community.qnx.com/sf/sfmain/do/home, that's full of useful information and files.
Before we talk about which method you should use, there are a few things you can do to make the turnaround time on your bug report much shorter.
