/SUBSYSTEM (Specify Subsystem)

/SUBSYSTEM:{BOOT_APPLICATION|CONSOLE|EFI_APPLICATION|
            EFI_BOOT_SERVICE_DRIVER|EFI_ROM|EFI_RUNTIME_DRIVER|NATIVE|
            POSIX|WINDOWS)
            [,major[.minor]]

• BOOT_APPLICATION
  An application that runs in the Windows boot environment. For more information about boot applications, see About BCD.

• CONSOLE
  Win32 character-mode application. The operating system provides a console for console applications. If main or wmain is defined for native code, int main(array<String ^> ^) is defined for managed code, or you build the application completely by using /clr:safe, CONSOLE is the default.

• Extensible Firmware Interface
  The EFI_* subsystems. See the EFI specification for more information. For example, see the Intel Web site. The minimum version and default version is 1.0.

• NATIVE
  Kernel mode drivers for Windows NT. This option is usually reserved for Windows system components. If /DRIVER:WDM is specified, NATIVE is the default.

• POSIX
  Application that runs with the POSIX subsystem in Windows NT.

• WINDOWS
  Application does not require a console, probably because it creates its own windows for interaction with the user. If WinMain or wWinMain is defined for native code, or WinMain(HISTANCE *, HINSTANCE *, char *, int) or wWinMain(HINSTANCE *, HINSTANCE *, wchar_t *, int) is defined for managed code, WINDOWS is the default.

• Major and minor (optional)
  Specify the minimum required version of the subsystem. The arguments are decimal numbers in the range 0 through 65,535. See the Remarks for more information. There are no upper bounds for version numbers.

Remarks

The /SUBSYSTEM option specifies the environment for the executable.

The choice of subsystem affects the entry point symbol (or entry point function) that the linker will select.

The optional minimum and default major and minor version numbers for the subsystems are as follows.
