I am developing an application that needs to work on Linux, Windows and Mac OS X. To that purpose, I am using C++ with Qt.

For many reasons, on Mac OS X, I need to use CoreFoundation functions (such as CFBundleCopyBundleURL) that creates core objects that need to be released with CFRelease. But doing so generate a lots of these warnings:

*** __NSAutoreleaseNoPool(): Object 0x224f7e0 of class NSURL autoreleased with no pool in place - just leaking

All the code I've seen concerning these autorelease pools are written in Objective-C. Does anybody know how to create/use autorelease pools in C or C++?
