968 *@@ appBuildProgDetails:
969 * extracted code from appStartApp to fix the
970 * given PROGDETAILS data to support the typical
971 * WPS stuff and allocate a single block of
972 * shared memory containing all the data.
973 *
974 * This is now used by XWP's progOpenProgram
975 * directly as a temporary fix for all the
976 * session hangs.
977 *
978 * As input, this takes a PROGDETAILS structure,
979 * which is converted in various ways. In detail,
980 * this supports:
981 *
982 * -- starting "*" executables (command prompts
983 * for OS/2, DOS, Win-OS/2);
984 *
985 * -- starting ".CMD" and ".BAT" files as
986 * PROGDETAILS.pszExecutable; for those, we
987 * convert the executable and parameters to
988 * start CMD.EXE or COMMAND.COM with the "/C"
989 * parameter instead;
990 *
991 * -- starting apps which are not fully qualified
992 * and therefore assumed to be on the PATH
993 * (for which doshSearchPath("PATH") is called).
994 *
995 * Unless it is "*", PROGDETAILS.pszExecutable must
996 * be a proper file name. The full path may be omitted
997 * if it is on the PATH, but the extension (.EXE etc.)
998 * must be given. You can use doshFindExecutable to
999 * find executables if you don't know the extension.
1000 *
1001 * This also handles and merges special and default
1002 * environments for the app to be started. The
1003 * following should be respected:
1004 *
1005 * -- As with WinStartApp, if PROGDETAILS.pszEnvironment
1006 * is NULL, the new app inherits the default environment
1007 * from the shell.
1008 *
1009 * -- However, if you specify an environment, you _must_
1010 * specify a complete environment. This function
1011 * will not merge environments. Use
1012 * appSetEnvironmentVar to change environment
1013 * variables in a complete environment set.
1014 *
1015 * -- If PROGDETAILS specifies a Win-OS/2 session
1016 * and PROGDETAILS.pszEnvironment is empty,
1017 * this uses the default Win-OS/2 environment
1018 * from OS2.INI. See appQueryDefaultWin31Environment.
1019 *
1020 * Even though this isn't clearly said in PMREF,
1021 * PROGDETAILS.swpInitial is important:
1022 *
1023 * -- To start a session minimized, set fl to SWP_MINIMIZE.
1024 *
1025 * -- To start a VIO session with auto-close disabled,
1026 * set the half-documented SWP_NOAUTOCLOSE flag (0x8000)
1027 * This flag is now in the newer toolkit headers.
1028 *
1029 * In addition, this supports the following session
1030 * flags with ulFlags if PROG_DEFAULT is specified:
1031 *
1032 * -- APP_RUN_FULLSCREEN: start a fullscreen session
1033 * for VIO, DOS, and Win-OS/2 programs. Otherwise
1034 * we start a windowed or (share) a seamless session.
1035 * Ignored if the program is PM.
1036 *
1037 * -- APP_RUN_ENHANCED: for Win-OS/2 sessions, use
1038 * enhanced mode.
1039 * Ignored if the program is not Win-OS/2.
1040 *
1041 * -- APP_RUN_STANDARD: for Win-OS/2 sessions, use
1042 * standard mode.
1043 * Ignored if the program is not Win-OS/2.
1044 *
1045 * -- APP_RUN_SEPARATE: for Win-OS/2 sessions, use
1046 * a separate session.
1047 * Ignored if the program is not Win-OS/2.
1048 *
1049 * If NO_ERROR is returned, *ppDetails receives a
1050 * new buffer of shared memory containing all the
1051 * data packed together.
1052 *
1053 * The shared memory is allocated unnamed and
1054 * with OBJ_GETTABLE. It is the responsibility
1055 * of the caller to call DosFreeMem on that buffer.

1780 *@@ appStartApp:
1781 * wrapper around WinStartApp which fixes the
1782 * specified PROGDETAILS to (hopefully) work
1783 * work with all executable types.
1784 *
1785 * This first calls appBuildProgDetails (see
1786 * remarks there) and then calls WinStartApp.
1787 *
1788 * Since this calls WinStartApp in turn, this
1789 * requires a message queue on the calling thread.
1790 *
1791 * Note that this also does minimal checking on
1792 * the specified parameters so it can return something
1793 * more meaningful than FALSE like WinStartApp.
1794 * As a result, you get a DOS error code now (V0.9.16).
1795 *
1796 * Most importantly:
1797 *
1798 * -- ERROR_INVALID_THREADID: not running on thread 1.
1799 * See remarks below.
1800 *
1801 * -- ERROR_NOT_ENOUGH_MEMORY
1802 *
1803 * plus the many error codes from appBuildProgDetails,
1804 * which gets called in turn.
1805 *
1806 * <B>About enforcing thread 1</B>
1807 *
1808 * OK, after long, long debugging hours, I have found
1809 * that WinStartApp hangs the system in the following
1810 * cases hard:
1811 *
1812 * -- If a Win-OS/2 session is started and WinStartApp
1813 * is _not_ on thread 1. For this reason, we check
1814 * if the caller is trying to start a Win-OS/2
1815 * session and return ERROR_INVALID_THREADID if
1816 * this is not running on thread 1.
1817 *
1818 * -- By contrast, there are many situations where
1819 * calling WinStartApp from within the Workplace
1820 * process will hang the system, most notably
1821 * with VIO sessions. I have been unable to figure
1822 * out why this happens, so XWorkplace now uses
1823 * its daemon to call WinStartApp instead.
1824 *
1825 * As a word of wisdom, do not call this from
1826 * within the Workplace process. For some strange
1827 * reason though, the XWorkplace "Run" dialog
1828 * (which uses this) _does_ work. Whatever.
