写一段获取CmpTraceRoutine函数的代码

获取CmpTraceRoutine函数的代码可能因操作系统版本和架构而异，以下是获取CmpTraceRoutine函数的示例代码，适用于Windows 10 64位操作系统：

#include <windows.h>
#include <winternl.h>

int main()
{
    HMODULE ntdll = LoadLibraryA("ntdll.dll");
    if (ntdll == NULL)
    {
        return -1;
    }

    PRTL_PROCESS_MODULES modules = NULL;
    ULONG size = 0;
    NTSTATUS status = ((NTSTATUS(WINAPI*)(HANDLE, DWORD, PVOID, ULONG, PULONG))GetProcAddress(ntdll, "NtQuerySystemInformation"))(SystemModuleInformation, NULL, 0, &size);
    if (status != STATUS_INFO_LENGTH_MISMATCH)
    {
        FreeLibrary(ntdll);
        return -1;
    }

    modules = (PRTL_PROCESS_MODULES)VirtualAlloc(NULL, size, MEM_COMMIT | MEM_RESERVE, PAGE_READWRITE);
    if (modules == NULL)
    {
        FreeLibrary(ntdll);
        return -1;
    }

    status = ((NTSTATUS(WINAPI*)(HANDLE, DWORD, PVOID, ULONG, PULONG))GetProcAddress(ntdll, "NtQuerySystemInformation"))(SystemModuleInformation, modules, size, &size);
    if (status != 0)
    {
        VirtualFree(modules, 0, MEM_RELEASE);
        FreeLibrary(ntdll);
        return -1;
    }

    PRTL_PROCESS_MODULE_INFORMATION module = modules->Modules;
    for (ULONG i = 0; i < modules->NumberOfModules; i++)
    {
        if (_stricmp(module->FullPathName + module->OffsetToFileName, "ntoskrnl.exe") == 0)
        {
            HMODULE ntoskrnl = LoadLibraryExA(module->FullPathName, NULL, DONT_RESOLVE_DLL_REFERENCES);
            if (ntoskrnl == NULL)
            {
                break;
            }

            PVOID address = GetProcAddress(ntoskrnl, "CmpTraceRoutine");
            if (address != NULL)
            {
                // CmpTraceRoutine 函数的地址在 address 中
                break;
            }

            FreeLibrary(ntoskrnl);
        }

        module++;
    }

    VirtualFree(modules, 0, MEM_RELEASE);
    FreeLibrary(ntdll);

    return 0;
}

这段代码使用了Windows系统内部的API函数`NtQuerySystemInformation`和`RtlProcessModules`来枚举操作系统中加载的模块，找到`ntoskrnl.exe`模块并加载，然后在该模块中搜索`CmpTraceRoutine`函数的地址。请注意，此代码仅供参考，如果你要在实际应用中使用，请根据具体情况进行适当修改。
