I am using Xcode for debugging of my C program, and I want to make sure that all memory allocations has been freed when the program is finished. 我正在使用Xcode调试我的C程序，并且我想确保在程序完成时已释放所有内存分配。 However, I am not sure how can I see if there is any alloc that is left not freed. 但是，我不确定如何查看是否有任何未释放的分配。

I know that it is possible to do using Valgrind on machines running on Linux. 我知道可以在Linux上运行的计算机上使用Valgrind。 Would appreciate if someone suggests alternative for Mac OS X Yosemite 10.10.1 and it would be even better if there is a way of doing it on Xcode. 如果有人建议使用Mac OS X Yosemite 10.10.1的替代方案，并且如果在Xcode上可以做到这一点，那就更好了。

When I am looking at memory accumulation (not being released) I use the Xcode profiler and Heap Shot, see For HowTo use Heap Shot (now named Mark Generation) to find memory creap: bbum blog . 当我查看内存累积（未发布）时，我使用Xcode探查器和Heap Shot，请参阅“如何使用Heap Shot（现在称为Mark Generation）”来查找内存问题： bbum blog 。

Also see the memory diagnostics under "Edit Scheme""Diagnostics": Enable Scribble, Enable Guard Edges, Enable Guard Malloc and Malloc Stack. 另请参见“编辑方案”“诊断”下的内存诊断：启用涂抹，启用保护边缘，启用保护Malloc和Malloc堆栈。

valgrind is available on MacOS. valgrind在MacOS上可用。 See valgrind web site: "X86/Darwin and AMD64/Darwin (Mac OS X 10.9, with limited support for 10.8)." 请参阅valgrind网站：“ X86 / Darwin和AMD64 / Darwin（Mac OS X 10.9，有限支持10.8）。”

So, that looks a good alternative to valgrind on linux, if you want to use MacOS. 因此，如果您要使用MacOS，那似乎是linux上valgrind的不错选择。
