1053 *@@ appBuildProgDetails:
1054 * extracted code from appStartApp to fix the
1055 * given PROGDETAILS data to support the typical
1056 * WPS stuff and allocate a single block of
1057 * shared memory containing all the data.
1058 *
1059 * This is now used by XWP's progOpenProgram
1060 * directly as a temporary fix for all the
1061 * session hangs.
1062 *
1063 * As input, this takes a PROGDETAILS structure,
1064 * which is converted in various ways. In detail,
1065 * this supports:
1066 *
1067 * -- starting "*" executables (command prompts
1068 * for OS/2, DOS, Win-OS/2);
1069 *
1070 * -- starting ".CMD" and ".BAT" files as
1071 * PROGDETAILS.pszExecutable; for those, we
1072 * convert the executable and parameters to
1073 * start CMD.EXE or COMMAND.COM with the "/C"
1074 * parameter instead;
1075 *
1076 * -- starting apps which are not fully qualified
1077 * and therefore assumed to be on the PATH
1078 * (for which doshSearchPath("PATH") is called).
1079 *
1080 * Unless it is "*", PROGDETAILS.pszExecutable must
1081 * be a proper file name. The full path may be omitted
1082 * if it is on the PATH, but the extension (.EXE etc.)
1083 * must be given. You can use doshFindExecutable to
1084 * find executables if you don't know the extension.
1085 *
1086 * This also handles and merges special and default
1087 * environments for the app to be started. The
1088 * following should be respected:
1089 *
1090 * -- As with WinStartApp, if PROGDETAILS.pszEnvironment
1091 * is NULL, the new app inherits the default environment
1092 * from the shell.
1093 *
1094 * -- However, if you specify an environment, you _must_
1095 * specify a complete environment. This function
1096 * will not merge environments. Use
1097 * appSetEnvironmentVar to change environment
1098 * variables in a complete environment set.
1099 *
1100 * -- If PROGDETAILS specifies a Win-OS/2 session
1101 * and PROGDETAILS.pszEnvironment is empty,
1102 * this uses the default Win-OS/2 environment
1103 * from OS2.INI. See appQueryDefaultWin31Environment.
1104 *
1105 * Even though this isn't clearly said in PMREF,
1106 * PROGDETAILS.swpInitial is important:
1107 *
1108 * -- To start a session minimized, set fl to SWP_MINIMIZE.
1109 *
1110 * -- To start a VIO session with auto-close disabled,
1111 * set the half-documented SWP_NOAUTOCLOSE flag (0x8000)
1112 * This flag is now in the newer toolkit headers.
1113 *
1114 * In addition, this supports the following session
1115 * flags with ulFlags if PROG_DEFAULT is specified:
1116 *
1117 * -- APP_RUN_FULLSCREEN: start a fullscreen session
1118 * for VIO, DOS, and Win-OS/2 programs. Otherwise
1119 * we start a windowed or (share) a seamless session.
1120 * Ignored if the program is PM.
1121 *
1122 * -- APP_RUN_ENHANCED: for Win-OS/2 sessions, use
1123 * enhanced mode.
1124 * Ignored if the program is not Win-OS/2.
1125 *
1126 * -- APP_RUN_STANDARD: for Win-OS/2 sessions, use
1127 * standard mode.
1128 * Ignored if the program is not Win-OS/2.
1129 *
1130 * -- APP_RUN_SEPARATE: for Win-OS/2 sessions, use
1131 * a separate session.
1132 * Ignored if the program is not Win-OS/2.
1133 *
1134 * If NO_ERROR is returned, *ppDetails receives a
1135 * new buffer of shared memory containing all the
1136 * data packed together.
1137 *
1138 * The shared memory is allocated unnamed and
1139 * with OBJ_GETTABLE. It is the responsibility
1140 * of the caller to call DosFreeMem on that buffer.

1873 *@@ appStartApp:
1874 * wrapper around WinStartApp which fixes the
1875 * specified PROGDETAILS to (hopefully) work
1876 * work with all executable types.
1877 *
1878 * This first calls appBuildProgDetails (see
1879 * remarks there) and then calls WinStartApp.
1880 *
1881 * Since this calls WinStartApp in turn, this
1882 * requires a message queue on the calling thread.
1883 *
1884 * Note that this also does minimal checking on
1885 * the specified parameters so it can return something
1886 * more meaningful than FALSE like WinStartApp.
1887 * As a result, you get a DOS error code now (V0.9.16).
1888 *
1889 * Most importantly:
1890 *
1891 * -- ERROR_INVALID_THREADID: not running on thread 1.
1892 * See remarks below.
1893 *
1894 * -- ERROR_NOT_ENOUGH_MEMORY
1895 *
1896 * plus the many error codes from appBuildProgDetails,
1897 * which gets called in turn.
1898 *
1899 * <B>About enforcing thread 1</B>
1900 *
1901 * OK, after long, long debugging hours, I have found
1902 * that WinStartApp hangs the system in the following
1903 * cases hard:
1904 *
1905 * -- If a Win-OS/2 session is started and WinStartApp
1906 * is _not_ on thread 1. For this reason, we check
1907 * if the caller is trying to start a Win-OS/2
1908 * session and return ERROR_INVALID_THREADID if
1909 * this is not running on thread 1.
1910 *
1911 * -- By contrast, there are many situations where
1912 * calling WinStartApp from within the Workplace
1913 * process will hang the system, most notably
1914 * with VIO sessions. I have been unable to figure
1915 * out why this happens, so XWorkplace now uses
1916 * its daemon to call WinStartApp instead.
1917 *
1918 * As a word of wisdom, do not call this from
1919 * within the Workplace process. For some strange
1920 * reason though, the XWorkplace "Run" dialog
1921 * (which uses this) _does_ work. Whatever.
