828 *@@ appStartApp:
829 * wrapper around WinStartApp which fixes the
830 * specified PROGDETAILS to (hopefully) work
831 * work with all executable types.
832 *
833 * This fixes the executable info to support:
834 *
835 * -- starting "*" executables (command prompts
836 * for OS/2, DOS, Win-OS/2);
837 *
838 * -- starting ".CMD" and ".BAT" files as
839 * PROGDETAILS.pszExecutable;
840 *
841 * -- starting apps which are not fully qualified
842 * and therefore assumed to be on the PATH.
843 *
844 * Unless it is "*", PROGDETAILS.pszExecutable must
845 * be a proper file name. The full path may be omitted
846 * if it is on the PATH, but the extension (.EXE etc.)
847 * must be given. You can use doshFindExecutable to
848 * find executables if you don't know the extension.
849 *
850 * This also handles and merges special and default
851 * environments for the app to be started. The
852 * following should be respected:
853 *
854 * -- As with WinStartApp, if PROGDETAILS.pszEnvironment
855 * is NULL, the new app inherits a default environment
856 * from the shell.
857 *
858 * -- However, if you specify an environment, you _must_
859 * specify a complete environment. This function
860 * will not merge environments. Use
861 * appSetEnvironmentVar to change environment
862 * variables in a complete environment set.
863 *
864 * -- If PROGDETAILS specifies a Win-OS/2 session
865 * and PROGDETAILS.pszEnvironment is empty,
866 * this uses the default Win-OS/2 environment.
867 * See appQueryDefaultWin31Environment.
868 *
869 * Even though this isn't clearly said in PMREF,
870 * PROGDETAILS.swpInitial is important:
871 *
872 * -- To start a session minimized, set SWP_MINIMIZE.
873 *
874 * -- To start a VIO session with auto-close disabled,
875 * set the half-documented SWP_NOAUTOCLOSE flag (0x8000)
876 * This flag is now in the newer toolkit headers.
877 *
878 * In addition, this supports the following session
879 * flags with ulFlags if PROG_DEFAULT is specified:
880 *
881 * -- APP_RUN_FULLSCREEN
882 *
883 * -- APP_RUN_ENHANCED
884 *
885 * -- APP_RUN_STANDARD
886 *
887 * -- APP_RUN_SEPARATE
888 *
889 * Since this calls WinStartApp in turn, this
890 * requires a message queue on the calling thread.
891 *
892 * Note that this also does minimal checking on
893 * the specified parameters so it can return something
894 * more meaningful than FALSE like WinStartApp.
895 * As a result, you get a DOS error code now (V0.9.16).
896 *
897 * Most importantly:
898 *
899 * -- ERROR_INVALID_THREADID: not running on thread 1.
900 * Since this uses WinStartApp internally and
901 * WinStartApp completely hangs the session manager
902 * if a Win-OS/2 full-screen session is started from
903 * a thread that is NOT thread 1, this will now fail
904 * with this error for safety (V0.9.16).
905 *
906 * -- ERROR_INVALID_PARAMETER: pcProgDetails or
907 * phapp is NULL; or PROGDETAILS.pszExecutable is NULL.
908 *
909 * -- ERROR_FILE_NOT_FOUND, ERROR_PATH_NOT_FOUND:
910 * PROGDETAILS.pszExecutable and/or PROGDETAILS.pszStartupDir
911 * are invalid.
912 * A NULL PROGDETAILS.pszStartupDir is supported though.
