Win7 VC6.0下用GetAdaptersAddresses获取MAC地址失败

zenithcui 2014-07-16 04:50:02

在WinXP下，VC6.0调用GetAdaptersAddresses可以获取到本地MAC地址，
在Win7下，VC6.0调用GetAdaptersAddresses返回ERROR_INVALID_DATA。
在论坛上看到有人跟我遇到的问题一样，但是没有说怎么解决，哪位大侠知道是怎么回事，帮忙指点下，不胜感激。

这段示例代码看了无数遍，函数调用没有问题。我自己写一个小的测试程序，也可以正常获取到MAC地址，但是在我们的工程里调用就用问题。我看到http://connect.microsoft.com/VisualStudio/feedback/details/665383/getadaptersaddresses-api-incorrectly-returns-no-adapters-for-a-process-with-high-memory-consumption这个帖子上说getadaptersaddresses这个函数有bug，在程序消耗内存太大时可能有问题，但是我返回的值是ERROR_INVALID_DATA，不是ERROR_NOACCESS，貌似和这个帖子说的还不是一回事。我们的工程和我写的测试程序运行时消耗的内存相差20000KB，难道真是因为消耗的内存太大时这个函数有BUG

以上代码我默认为你的地址为IPv4，如果不行手动改写上面的代码为IPV6看看。如果还不行，那就是VC6.0的问题，我的正常获取，WIN7，64位，在WIN7 32位虚拟机也测试过。正常。我的VS版本VS2010
