I think you made a slight mistake in your test program. Execution control
is given to thread 1 in case of process termination. All other threads will
be terminated and stack will be reset by the OS. If your "beeping" thread
was in "beeping state" when terminated, it beeps forever... ;-))

VJ> This is certainly not true for VIO programs.  I switched to a PM program

This _is_ true. I'll supply some sample code for you wich _will_ work as an
VIO process. It will return the OS-defined values for exiting or termination
by kill _or shutdown!_ You may want to examine...

No, no!

May be, you should have a closer look on the following topics in the manuals:

- DosShutdown
- WinCancelShutdown
- WinShutdownSystem


There are different "levels" of shutdown in OS/2. You should refer to the
Control Program Programming Guide and Reference.


VJ> I would, however, still prefer a solution for a VIO program and if you

I will merge the code _NOW_ and I hope again it'll help:

/* Start of sample */

#define INCL_DOS
#define INCL_DOSPROCESS

#include 
#include 

VOID APIENTRY Termination ( ULONG ulTermCode );


INT main ( VOID )

{
  ULONG i = 0;

  DosExitList ( EXLST_ADD, (PFNEXITLIST) Termination );
                                             /* Installs exitlist function */

  printf ( "\nInnocent Victim, Ver 1.0" );
  printf ( "\nWaiting to be killed or have to kill myself!" );

  while ( i++ < 60 ){
    DosSleep ( 1000L );
    printf ( "." );
    flushall ();
  }

  DosExit ( EXIT_PROCESS, 0 );
  return (0); /* Supress warning */
}


VOID APIENTRY Termination ( ULONG ulTermCode )

{

   switch ( ulTermCode ) {

     case TC_EXIT:              /* Normal termination */
       printf ( "\nTermination Code: TC_EXIT\n" );
       break;
     case TC_KILLPROCESS:       /* Killed by tasklist or killed by shutdown */
       printf ( "\nTermination Code: TC_KILLPROCESS\n" );
       break;
     case TC_HARDERROR:         /* RTFM */
       printf ( "\nTermination Code: TC_HARDERROR\n" );
       break;
     case TC_TRAP:              /* RTFM */
       printf ( "\nTermination Code: TC_TRAP\n" );
       break;
     default:                   /* Never seen */
       printf ( "\nUnknown Termination Code: %d\n", ulTermCode );
       break;
   }

   printf ( "\nNow waiting 15 sec in exitlist-function before
terminating...\n" );
   DosSleep ( 15000L ); /* Exitlist processing _should_ be shorter, of course! */


   DosExitList ( EXLST_EXIT, 0 ); /* continue with next function in list */

}


/* End of sample */

The _same_ galaxy, I'd used to live in! (...most of my time...)



Bye/2

Stephan
