This doesn't seem to be a valid error code according to the header files. 
Are you sure you're displaying it correctly?

The following is a fragment of code that provides a simple 
example of the use of DosStartSession.
 
/*
 * Start the specified program as a separate, unrelated, background
 * session. 
 *
 * Parameters are name of program, which must include extension and must
 * either be in the search path or include fully specified path, and
 * argument string to pass to it.  Argument string may be specified as 
 * NULL, otherwise it a single 0-terminated string constituting the 
 * "tail" of a command line for the program.
 */
void FAR
StartSession(NPSZ npszName, PSZ pszArgs)
   STARTDATA       stdata;
   USHORT          idSession;
   int             rc;

   WtiLFillStruct(&stdata, sizeof(stdata), 0);  /* zero-fill the struct */
   stdata.Related = FALSE;
   stdata.Length = sizeof(stdata);
   stdata.FgBg = TRUE;
   stdata.PgmName = npszName;
   stdata.PgmInputs = pszArgs;

   if (rc = DosStartSession(&stdata, &idSession, &pid)) 
      fprintf(stderr, "rc=%d from DosStartSession\n", rc);
}
