我如何更新我的流程?

比如说,当我的进程被创建时 STARTUPINFOEX 结构和 PROC_THREAD_ATTRIBUTE_LIST 成员:

DWORD ProtectionLevel = PROTECTION_LEVEL_SAME;
SIZE_T AttributeListSize;
STARTUPINFOEXW StartupInfoEx = { 0 };


StartupInfoEx.StartupInfo.cb = sizeof(StartupInfoEx);


InitializeProcThreadAttributeList(NULL, 1, 0, &AttributeListSize)


StartupInfoEx.lpAttributeList = (LPPROC_THREAD_ATTRIBUTE_LIST) HeapAlloc(
GetProcessHeap(),
0,
AttributeListSize
);


if (InitializeProcThreadAttributeList(StartupInfoEx.lpAttributeList,
1,
0,
&AttributeListSize) == FALSE)
{
Result = GetLastError();
goto exitFunc;
}


if (UpdateProcThreadAttribute(StartupInfoEx.lpAttributeList,
0,
PROC_THREAD_ATTRIBUTE_PROTECTION_LEVEL,
&ProtectionLevel,
sizeof(ProtectionLevel),
NULL,
NULL) == FALSE)
{
Result = GetLastError();
goto exitFunc;
}


PROCESS_INFORMATION ProcessInformation = { 0 };


if (CreateProcessW(ApplicationName,
CommandLine,
ProcessAttributes,
ThreadAttributes,
InheritHandles,
EXTENDED_STARTUPINFO_PRESENT | CREATE_PROTECTED_PROCESS,
Environment,
CurrentDirectory,
(LPSTARTUPINFOW)&StartupInfoEx,
&ProcessInformation) == FALSE)
{
Result = GetLastError();
goto exitFunc;
}

如何更新我自己进程的属性列表?

例如,我想修改我自己的流程' PROC_THREAD_ATTRIBUTE_CHILD_PROCESS_POLICY 以防止它创建任何子进程。
