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",
. . .
);
In either case, you must make sure that the first OS/2 application started
after booting your system is the one you want to run as a service.
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.
