当我尝试检查某个进程是否正在使用数据执行保护 (DEP) 时,我收到错误 87 (INVALID_PARAMETER)。我检查了我的代码,它似乎没问题,但不幸的是我仍然有同样的错误。
代码:
BOOL var = true;
DWORD dwPolicy;
HANDLE hProc = OpenProcess(PROCESS_QUERY_INFORMATION, false, 3624);
if (hProc == NULL) {
cout << "Can't open Process because of the error " << GetLastError() << endl;
}
if (GetProcessDEPPolicy(hProc, &dwPolicy, 0) != FALSE) {
if (dwPolicy == PROCESS_DEP_ENABLE) {
cout << "For try.exe process data execution prevention is enabled" << endl;
}
else if (dwPolicy == NULL) {
cout << "For try.exe process data execution prevention is disabled" << endl;
}
else {
cout << "Data is thrunked and we can't change DEP value in future" << endl;
}
}
else {
cout << "There was an error with discovering DEP in try.exe process because of "<<GetLastError() << endl;
}
编译执行后得到:
There was an error with discovering DEP in try.exe process because of 87
最佳答案
查看文档,函数GetProcessDEPPolicy
定义:
BOOL WINAPI GetProcessDEPPolicy(
_In_ HANDLE hProcess,
_Out_ LPDWORD lpFlags,
_Out_ PBOOL lpPermanent
);
请注意,最后一个参数是一个输出参数,它不是可选的,但您传递的是 0,也就是 NULL
。调用应该是:
BOOL permanent = FALSE;
if (GetProcessDEPPolicy(hProc, &dwPolicy, &permanent) != FALSE) {
关于c++ - GetProcessDEPPolicy 错误 87,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/37889449/
