How to Allow OS/2 Programs to Run Across Logons

• Microsoft Win32 Application Programming Interface (API) included with:

      - Microsoft Windows NT versions 3.51 and 4.00
  

SUMMARY

When you launch an OS/2 application from a service in Windows NT, the OS/2 application terminates when the current user logs off. If you want the application to continue running after the user logs off, you can:

• Run the OS/2 application from the Windows NT Resource Kit utility called SRVANY.

  -or-

• Launch Os2.exe directly from the service, and pass the /S switch. The syntax of the call would be:

  CreateProcess (

        NULL,
        "OS2.EXE /S /P <full path to exe> /C <command line>",
        . . .
        );
  

  The <command line> includes the name of the executable. For example:

        CreateProcess (
           NULL,
           "OS2.EXE /S /P C:\\OS2BINS\\LS.EXE /C LS *.c",
           . . .
           );
  
  

MORE INFORMATION

The OS/2 Subsystem automatically shuts down when a user logs off. Using the /S switch on the Os2.exe command line tells the OS/2 Subsystem that it is running in the context of a service. The Subsystem then continues to run across logons.

The reason the application must be the first OS/2 executable launched is that if an OS/2 Subsystem server is present, it will be used rather than starting a new one to run as a service.

Any OS/2 applications launched by the interactive user will still be terminated upon logoff.
