Quick Q&A:
________
Q: What do I have to do to use this demo?
A: Put QC in your Control Panels folder and reboot your Mac. If the demo has expired contact us at one of the online addresses listed above.
Q: Can I use QC to test existing applications without rebuilding them?
A: Yes. QC was designed to test applications without requiring any modifications to the code. The release version of QC includes an optional application programming interface (QCAPI) that programmers can use to control QC testing directly from their code.
Q: How does QC report errors it finds?
A: QC reports detected errors through the use of a low level debugger. QC uses the _DebugStr trap to cause a user break into your favorite debugger. QC is fully compatible with MacsBug, TMON, TMON PRO, The Debugger, SourceBug, SADE, THINK C, CodeWarrior, MPW, etc. If you turn off debug breaks in the list of options, QC will emit a short distinctive beep when errors are detected.
Q: Does QC work on a Power Macintosh?
A: Yes. However, two incompatible tests are disabled if you are using the Modern Memory Manager. Those tests are 'Block Bounds Checking' and 'Invalidate Free Memory'. The next release of QC will be a native PowerPC application and will be available as a free upgrade to existing users.
Q: How does QC compare with tools such as Even Better Bus Error and the debugging version of Figment?
A: QC offers tests that are not available anywhere else. It performs many tests much faster than other testing tools. All QC's tests are integrated into a single INIT/cdev combination. A Macintosh interface makes QC usable right out of the box. QC's API can be used to fine tune testing to specific areas of code (new code or suspect code, for example). QC reports more information when an error is found.
Q: What do I get when I purchase QC?
A: The following is contained on the release disk. A fully licensed copy of QC for single machine use and complete documentation. The QC Application Programming Interface (QCAPI) libraries and interfaces for those who want to control QC testing directly from their code. Full source code to an application called BadAPPL that illustrates what QC detects as well as how to use the QCAPI. The disk also contains some assorted free utilities.
Q: How can I obtain QC?
