983 *@@ appBuildProgDetails:

985 * given PROGDETAILS data to support the typical
986 * WPS stuff and allocate a single block of
987 * shared memory containing all the data.
988 *
989 * This is now used by XWP's progOpenProgram
990 * directly as a temporary fix for all the
991 * session hangs.
992 *
993 * As input, this takes a PROGDETAILS structure,
994 * which is converted in various ways. In detail,
995 * this supports:
996 *
997 * -- starting "*" executables (command prompts
998 * for OS/2, DOS, Win-OS/2);
999 *
1000 * -- starting ".CMD" and ".BAT" files as
1001 * PROGDETAILS.pszExecutable; for those, we
1002 * convert the executable and parameters to
1003 * start CMD.EXE or COMMAND.COM with the "/C"
1004 * parameter instead;
1005 *
1006 * -- starting apps which are not fully qualified
1007 * and therefore assumed to be on the PATH
1008 * (for which doshSearchPath("PATH") is called).
1009 *
1010 * Unless it is "*", PROGDETAILS.pszExecutable must
1011 * be a proper file name. The full path may be omitted
1012 * if it is on the PATH, but the extension (.EXE etc.)
1013 * must be given. You can use doshFindExecutable to
1014 * find executables if you don't know the extension.
1015 *
1016 * This also handles and merges special and default
1017 * environments for the app to be started. The
1018 * following should be respected:
1019 *
1020 * -- As with WinStartApp, if PROGDETAILS.pszEnvironment
1021 * is NULL, the new app inherits the default environment
1022 * from the shell.
1023 *
1024 * -- However, if you specify an environment, you _must_
1025 * specify a complete environment. This function
1026 * will not merge environments. Use
1027 * appSetEnvironmentVar to change environment
1028 * variables in a complete environment set.
1029 *
1030 * -- If PROGDETAILS specifies a Win-OS/2 session
1031 * and PROGDETAILS.pszEnvironment is empty,
1032 * this uses the default Win-OS/2 environment
1033 * from OS2.INI. See appQueryDefaultWin31Environment.
1034 *
1035 * Even though this isn't clearly said in PMREF,
1036 * PROGDETAILS.swpInitial is important:
1037 *
1038 * -- To start a session minimized, set fl to SWP_MINIMIZE.
1039 *
1040 * -- To start a VIO session with auto-close disabled,
1041 * set the half-documented SWP_NOAUTOCLOSE flag (0x8000)
1042 * This flag is now in the newer toolkit headers.
1043 *
1044 * In addition, this supports the following session
1045 * flags with ulFlags if PROG_DEFAULT is specified:
1046 *
1047 * -- APP_RUN_FULLSCREEN: start a fullscreen session
1048 * for VIO, DOS, and Win-OS/2 programs. Otherwise
1049 * we start a windowed or (share) a seamless session.
1050 * Ignored if the program is PM.
1051 *
1052 * -- APP_RUN_ENHANCED: for Win-OS/2 sessions, use
1053 * enhanced mode.
1054 * Ignored if the program is not Win-OS/2.
1055 *
1056 * -- APP_RUN_STANDARD: for Win-OS/2 sessions, use
1057 * standard mode.
1058 * Ignored if the program is not Win-OS/2.
1059 *
1060 * -- APP_RUN_SEPARATE: for Win-OS/2 sessions, use
1061 * a separate session.
1062 * Ignored if the program is not Win-OS/2.
1063 *
1064 * If NO_ERROR is returned, *ppDetails receives a
1065 * new buffer of shared memory containing all the
1066 * data packed together.
1067 *
1068 * The shared memory is allocated unnamed and
1069 * with OBJ_GETTABLE. It is the responsibility
1070 * of the caller to call DosFreeMem on that buffer.

1811 *@@ appStartApp:
1812 * wrapper around WinStartApp which fixes the
1813 * specified PROGDETAILS to (hopefully) work
1814 * work with all executable types.
1815 *
1816 * This first calls appBuildProgDetails (see
1817 * remarks there) and then calls WinStartApp.
1818 *
1819 * Since this calls WinStartApp in turn, this
1820 * requires a message queue on the calling thread.
1821 *
1822 * Note that this also does minimal checking on
1823 * the specified parameters so it can return something
1824 * more meaningful than FALSE like WinStartApp.
1825 * As a result, you get a DOS error code now (V0.9.16).
1826 *
1827 * Most importantly:
1828 *
1829 * -- ERROR_INVALID_THREADID: not running on thread 1.
1830 * See remarks below.
1831 *
1832 * -- ERROR_NOT_ENOUGH_MEMORY
1833 *
1834 * plus the many error codes from appBuildProgDetails,
1835 * which gets called in turn.
1836 *
1837 * <B>About enforcing thread 1</B>
1838 *
1839 * OK, after long, long debugging hours, I have found
1840 * that WinStartApp hangs the system in the following
1841 * cases hard:
1842 *
1843 * -- If a Win-OS/2 session is started and WinStartApp
1844 * is _not_ on thread 1. For this reason, we check
1845 * if the caller is trying to start a Win-OS/2
1846 * session and return ERROR_INVALID_THREADID if
1847 * this is not running on thread 1.
1848 *
1849 * -- By contrast, there are many situations where
1850 * calling WinStartApp from within the Workplace
1851 * process will hang the system, most notably
1852 * with VIO sessions. I have been unable to figure
1853 * out why this happens, so XWorkplace now uses
1854 * its daemon to call WinStartApp instead.
1855 *
1856 * As a word of wisdom, do not call this from
1857 * within the Workplace process. For some strange
1858 * reason though, the XWorkplace "Run" dialog
1859 * (which uses this) _does_ work. Whatever.
