/target switch
The /target switch enables the MIDL compiler to enable optimizations available only on recent versions of Windows. The /target switch automatically activates additional switches.
midl /target level
Switch Options
-
level
-
Specifies the target level, such as NT50, NT51, NT60, NT61, NT62, or NT100.
Remarks
The /target switch automatically activates additional switches, based on the operating system, as specified in the following table:
| Operating system | /target level | Switches Activated |
|---|---|---|
| Windows 2000 | NT50 | /Oicf /error all /robust |
| Windows XP | NT51 | /Oicf /error all /robust /protocol all |
| Windows Vista | NT60 | /Oicf /error all /robust /protocol all |
| Windows 7 | NT61 | /Oicf /error all /robust /protocol all |
| Windows 8 | NT62 | /Oicf /error all /robust /protocol all |
| Windows 10 | NT100 | /Oicf /error all /robust /protocol all |
To ensure a stub runs on the system specified by the /target switch, MIDL issues an error when a feature available only on a more recent version of Windows is present. The following table specifies the minimum /target level required to enable the feature. Higher target levels include all features from lower target levels.
| Minimum required /target level | Features |
|---|---|
| NT50 | /robust [message] [async] [async_uuid] [notify] in /Oicf mode [encode] or [decode] in /Oicf mode |
| NT51 | /protocol 64-bit support [partial_ignore] [force_allocate] |
| NT60 | Forced complex structure marshalling Context handles in an array or structure [range] support for unsized strings [type_strict_context_handle] |
| NT61 | Direct COM stub calls for interfaces with less than 32 methods requires linking COM stubs with OLE32.DLL. |
| NT62 | ARM support WinRT support |
| NT100 | [system_handle] support |
