int 2eh 方式调用Native api
小技巧。但是用的人好像不多。例子: Windows 2000 下
NtQuerySystemInformationNo = 0x97;
_declspec(naked)
NTSTATUS __stdcall PrivateNtQuerySystemInformation
    (IN     SYSTEM_INFORMATION_CLASS,
    IN OUT PVOID,
    IN     ULONG,
    OUT    PULONG OPTIONAL)
{
    _asm {
        mov eax, NtQuerySystemInformationNo
        lea edx, [esp+4]
        int 2Eh
        ret 10h
    }
