878 *@@ appStartApp:
879 * wrapper around WinStartApp which fixes the
880 * specified PROGDETAILS to (hopefully) work
881 * work with all executable types.
882 *
883 * This fixes the executable info to support:
884 *
885 * -- starting "*" executables (command prompts
886 * for OS/2, DOS, Win-OS/2);
887 *
888 * -- starting ".CMD" and ".BAT" files as
889 * PROGDETAILS.pszExecutable;
890 *
891 * -- starting apps which are not fully qualified
892 * and therefore assumed to be on the PATH.
893 *
894 * Unless it is "*", PROGDETAILS.pszExecutable must
895 * be a proper file name. The full path may be omitted
896 * if it is on the PATH, but the extension (.EXE etc.)
897 * must be given. You can use doshFindExecutable to
898 * find executables if you don't know the extension.
899 *
900 * This also handles and merges special and default
901 * environments for the app to be started. The
902 * following should be respected:
903 *
904 * -- As with WinStartApp, if PROGDETAILS.pszEnvironment
905 * is NULL, the new app inherits a default environment
906 * from the shell.
907 *
908 * -- However, if you specify an environment, you _must_
909 * specify a complete environment. This function
910 * will not merge environments. Use
911 * appSetEnvironmentVar to change environment
912 * variables in a complete environment set.
913 *
914 * -- If PROGDETAILS specifies a Win-OS/2 session
915 * and PROGDETAILS.pszEnvironment is empty,
916 * this uses the default Win-OS/2 environment.
917 * See appQueryDefaultWin31Environment.
918 *
919 * Even though this isn't clearly said in PMREF,
920 * PROGDETAILS.swpInitial is important:
921 *
922 * -- To start a session minimized, set SWP_MINIMIZE.
923 *
924 * -- To start a VIO session with auto-close disabled,
925 * set the half-documented SWP_NOAUTOCLOSE flag (0x8000)
926 * This flag is now in the newer toolkit headers.
927 *
928 * In addition, this supports the following session
929 * flags with ulFlags if PROG_DEFAULT is specified:
930 *
931 * -- APP_RUN_FULLSCREEN
932 *
933 * -- APP_RUN_ENHANCED
934 *
935 * -- APP_RUN_STANDARD
936 *
937 * -- APP_RUN_SEPARATE
938 *
939 * Since this calls WinStartApp in turn, this
940 * requires a message queue on the calling thread.
941 *
942 * Note that this also does minimal checking on
943 * the specified parameters so it can return something
944 * more meaningful than FALSE like WinStartApp.
945 * As a result, you get a DOS error code now (V0.9.16).
946 *
947 * Most importantly:
948 *
949 * -- ERROR_INVALID_THREADID: not running on thread 1.
950 * Since this uses WinStartApp internally and
951 * WinStartApp completely hangs the session manager
952 * if a Win-OS/2 full-screen session is started from
953 * a thread that is NOT thread 1, this will now fail
954 * with this error for safety (V0.9.16).
955 *
956 * -- ERROR_INVALID_PARAMETER: pcProgDetails or
957 * phapp is NULL; or PROGDETAILS.pszExecutable is NULL.
958 *
959 * -- ERROR_FILE_NOT_FOUND, ERROR_PATH_NOT_FOUND:
960 * PROGDETAILS.pszExecutable and/or PROGDETAILS.pszStartupDir
961 * are invalid.
962 * A NULL PROGDETAILS.pszStartupDir is supported though.
