1054 *@@ appBuildProgDetails:
1055 * extracted code from appStartApp to fix the
1056 * given PROGDETAILS data to support the typical
1057 * WPS stuff and allocate a single block of
1058 * shared memory containing all the data.
1059 *
1060 * This is now used by XWP's progOpenProgram
1061 * directly as a temporary fix for all the
1062 * session hangs.
1063 *
1064 * As input, this takes a PROGDETAILS structure,
1065 * which is converted in various ways. In detail,
1066 * this supports:
1067 *
1068 * -- starting "*" executables (command prompts
1069 * for OS/2, DOS, Win-OS/2);
1070 *
1071 * -- starting ".CMD" and ".BAT" files as
1072 * PROGDETAILS.pszExecutable; for those, we
1073 * convert the executable and parameters to
1074 * start CMD.EXE or COMMAND.COM with the "/C"
1075 * parameter instead;
1076 *
1077 * -- starting apps which are not fully qualified
1078 * and therefore assumed to be on the PATH
1079 * (for which doshSearchPath("PATH") is called).
1080 *
1081 * Unless it is "*", PROGDETAILS.pszExecutable must
1082 * be a proper file name. The full path may be omitted
1083 * if it is on the PATH, but the extension (.EXE etc.)
1084 * must be given. You can use doshFindExecutable to
1085 * find executables if you don't know the extension.
1086 *
1087 * This also handles and merges special and default
1088 * environments for the app to be started. The
1089 * following should be respected:
1090 *
1091 * -- As with WinStartApp, if PROGDETAILS.pszEnvironment
1092 * is NULL, the new app inherits the default environment
1093 * from the shell.
1094 *
1095 * -- However, if you specify an environment, you _must_
1096 * specify a complete environment. This function
1097 * will not merge environments. Use
1098 * appSetEnvironmentVar to change environment
1099 * variables in a complete environment set.
1100 *
1101 * -- If PROGDETAILS specifies a Win-OS/2 session
1102 * and PROGDETAILS.pszEnvironment is empty,
1103 * this uses the default Win-OS/2 environment
1104 * from OS2.INI. See appQueryDefaultWin31Environment.
1105 *
1106 * Even though this isn't clearly said in PMREF,
1107 * PROGDETAILS.swpInitial is important:
1108 *
1109 * -- To start a session minimized, set fl to SWP_MINIMIZE.
1110 *
1111 * -- To start a VIO session with auto-close disabled,
1112 * set the half-documented SWP_NOAUTOCLOSE flag (0x8000)
1113 * This flag is now in the newer toolkit headers.
1114 *
1115 * In addition, this supports the following session
1116 * flags with ulFlags if PROG_DEFAULT is specified:
1117 *
1118 * -- APP_RUN_FULLSCREEN: start a fullscreen session
1119 * for VIO, DOS, and Win-OS/2 programs. Otherwise
1120 * we start a windowed or (share) a seamless session.
1121 * Ignored if the program is PM.
1122 *
1123 * -- APP_RUN_ENHANCED: for Win-OS/2 sessions, use
1124 * enhanced mode.
1125 * Ignored if the program is not Win-OS/2.
1126 *
1127 * -- APP_RUN_STANDARD: for Win-OS/2 sessions, use
1128 * standard mode.
1129 * Ignored if the program is not Win-OS/2.
1130 *
1131 * -- APP_RUN_SEPARATE: for Win-OS/2 sessions, use
1132 * a separate session.
1133 * Ignored if the program is not Win-OS/2.
1134 *
1135 * If NO_ERROR is returned, *ppDetails receives a
1136 * new buffer of shared memory containing all the
1137 * data packed together.
1138 *
1139 * The shared memory is allocated unnamed and
1140 * with OBJ_GETTABLE. It is the responsibility
1141 * of the caller to call DosFreeMem on that buffer.

1887 *@@ appStartApp:
1888 * wrapper around WinStartApp which fixes the

1890 * work with all executable types.
1891 *
1892 * This first calls appBuildProgDetails (see
1893 * remarks there) and then calls WinStartApp.
1894 *
1895 * Since this calls WinStartApp in turn, this
1896 * requires a message queue on the calling thread.
1897 *
1898 * Note that this also does minimal checking on
1899 * the specified parameters so it can return something
1900 * more meaningful than FALSE like WinStartApp.
1901 * As a result, you get a DOS error code now (V0.9.16).
1902 *
1903 * Most importantly:
1904 *
1905 * -- ERROR_INVALID_THREADID: not running on thread 1.
1906 * See remarks below.
1907 *
1908 * -- ERROR_NOT_ENOUGH_MEMORY
1909 *
1910 * plus the many error codes from appBuildProgDetails,
1911 * which gets called in turn.
1912 *
1913 * <B>About enforcing thread 1</B>
1914 *
1915 * OK, after long, long debugging hours, I have found
1916 * that WinStartApp hangs the system in the following
1917 * cases hard:
1918 *
1919 * -- If a Win-OS/2 session is started and WinStartApp
1920 * is _not_ on thread 1. For this reason, we check
1921 * if the caller is trying to start a Win-OS/2
1922 * session and return ERROR_INVALID_THREADID if
1923 * this is not running on thread 1.
1924 *
1925 * -- By contrast, there are many situations where
1926 * calling WinStartApp from within the Workplace
1927 * process will hang the system, most notably
1928 * with VIO sessions. I have been unable to figure
1929 * out why this happens, so XWorkplace now uses
1930 * its daemon to call WinStartApp instead.
1931 *
1932 * As a word of wisdom, do not call this from
1933 * within the Workplace process. For some strange
1934 * reason though, the XWorkplace "Run" dialog
1935 * (which uses this) _does_ work. Whatever.
