我正在调试一个程序，想在secur32上设置一个断点！使用windbg模拟安全上下文。我的高级windows调试书告诉我，我应该能够使用这个命令设置断点。不幸的是，我失败了。
我确实检查过我的符号路径，我相信它是正确的。如果在windbg中运行bp Secur32!ImpersonateSecurityContext，我也会得到一些符号。

我只是在那里找不到符号。所以，我想这就是为什么我不能设定一个断点的原因。MSDN确实声称
x Secur32!*位于Secur32!ImpersonateSecurityContext内部。我不敢相信微软故意去掉这个符号，因为它是一个如此流行的功能，以至于许多程序都在使用它。我一定错过了一些简单的东西。有什么想法吗？
最佳答案
别无助。你已经有工具了。
如果您已经在调试一个调用ImpersonateSecurityContext的程序，那么找到对ImpersonateSecurityContext的调用，并查看call指令的目标是什么。
如果你没有一个调用ImpersonateSecurityContext的程序，那么去做一个。
#include <windows.h>
#include <security.h>
int __cdecl main(int, char **)
{
ImpersonateSecurityContext(NULL);
return 0;
}
编译这个程序，在
ImpersonateSecurityContext调用上设置一个断点，然后运行它。当断点命中时，只需一步查看它将带到哪里。这就是ImpersonateSecurityContext所在的位置。关于windows - 在Secur32!ImpersonateSecurityContext上设置断点，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/8003107/
