1037 *@@ appBuildProgDetails:
1038 * extracted code from appStartApp to fix the
1039 * given PROGDETAILS data to support the typical
1040 * WPS stuff and allocate a single block of
1041 * shared memory containing all the data.
1042 *
1043 * This is now used by XWP's progOpenProgram
1044 * directly as a temporary fix for all the
1045 * session hangs.
1046 *
1047 * As input, this takes a PROGDETAILS structure,
1048 * which is converted in various ways. In detail,
1049 * this supports:
1050 *
1051 * -- starting "*" executables (command prompts
1052 * for OS/2, DOS, Win-OS/2);
1053 *
1054 * -- starting ".CMD" and ".BAT" files as
1055 * PROGDETAILS.pszExecutable; for those, we
1056 * convert the executable and parameters to
1057 * start CMD.EXE or COMMAND.COM with the "/C"
1058 * parameter instead;
1059 *
1060 * -- starting apps which are not fully qualified
1061 * and therefore assumed to be on the PATH
1062 * (for which doshSearchPath("PATH") is called).
1063 *
1064 * Unless it is "*", PROGDETAILS.pszExecutable must
1065 * be a proper file name. The full path may be omitted
1066 * if it is on the PATH, but the extension (.EXE etc.)
1067 * must be given. You can use doshFindExecutable to
1068 * find executables if you don't know the extension.
1069 *
1070 * This also handles and merges special and default
1071 * environments for the app to be started. The
1072 * following should be respected:
1073 *
1074 * -- As with WinStartApp, if PROGDETAILS.pszEnvironment
1075 * is NULL, the new app inherits the default environment
1076 * from the shell.
1077 *
1078 * -- However, if you specify an environment, you _must_
1079 * specify a complete environment. This function
1080 * will not merge environments. Use
1081 * appSetEnvironmentVar to change environment
1082 * variables in a complete environment set.
1083 *
1084 * -- If PROGDETAILS specifies a Win-OS/2 session
1085 * and PROGDETAILS.pszEnvironment is empty,
1086 * this uses the default Win-OS/2 environment
1087 * from OS2.INI. See appQueryDefaultWin31Environment.
1088 *
1089 * Even though this isn't clearly said in PMREF,
1090 * PROGDETAILS.swpInitial is important:
1091 *
1092 * -- To start a session minimized, set fl to SWP_MINIMIZE.
1093 *
1094 * -- To start a VIO session with auto-close disabled,
1095 * set the half-documented SWP_NOAUTOCLOSE flag (0x8000)
1096 * This flag is now in the newer toolkit headers.
1097 *
1098 * In addition, this supports the following session
1099 * flags with ulFlags if PROG_DEFAULT is specified:
1100 *
1101 * -- APP_RUN_FULLSCREEN: start a fullscreen session
1102 * for VIO, DOS, and Win-OS/2 programs. Otherwise
1103 * we start a windowed or (share) a seamless session.
1104 * Ignored if the program is PM.
1105 *
1106 * -- APP_RUN_ENHANCED: for Win-OS/2 sessions, use
1107 * enhanced mode.
1108 * Ignored if the program is not Win-OS/2.
1109 *
1110 * -- APP_RUN_STANDARD: for Win-OS/2 sessions, use
1111 * standard mode.
1112 * Ignored if the program is not Win-OS/2.
1113 *
1114 * -- APP_RUN_SEPARATE: for Win-OS/2 sessions, use
1115 * a separate session.
1116 * Ignored if the program is not Win-OS/2.
1117 *
1118 * If NO_ERROR is returned, *ppDetails receives a
1119 * new buffer of shared memory containing all the
1120 * data packed together.
1121 *
1122 * The shared memory is allocated unnamed and
1123 * with OBJ_GETTABLE. It is the responsibility
1124 * of the caller to call DosFreeMem on that buffer.
1125 *
1126 * Returns:

1129 *
1130 * -- ERROR_INVALID_PARAMETER: pcProgDetails or

1857 *@@ appStartApp:
1858 * wrapper around WinStartApp which fixes the
1859 * specified PROGDETAILS to (hopefully) work
1860 * work with all executable types.
1861 *
1862 * This first calls appBuildProgDetails (see
1863 * remarks there) and then calls WinStartApp.
1864 *
1865 * Since this calls WinStartApp in turn, this
1866 * requires a message queue on the calling thread.
1867 *
1868 * Note that this also does minimal checking on
1869 * the specified parameters so it can return something
1870 * more meaningful than FALSE like WinStartApp.
1871 * As a result, you get a DOS error code now (V0.9.16).
1872 *
1873 * Most importantly:
1874 *
1875 * -- ERROR_INVALID_THREADID: not running on thread 1.
1876 * See remarks below.
1877 *
1878 * -- ERROR_NOT_ENOUGH_MEMORY
1879 *
1880 * plus the many error codes from appBuildProgDetails,
1881 * which gets called in turn.
1882 *
1883 * <B>About enforcing thread 1</B>
1884 *
1885 * OK, after long, long debugging hours, I have found
1886 * that WinStartApp hangs the system in the following
1887 * cases hard:
1888 *
1889 * -- If a Win-OS/2 session is started and WinStartApp
1890 * is _not_ on thread 1. For this reason, we check
1891 * if the caller is trying to start a Win-OS/2
1892 * session and return ERROR_INVALID_THREADID if
1893 * this is not running on thread 1.
1894 *
1895 * -- By contrast, there are many situations where
1896 * calling WinStartApp from within the Workplace
1897 * process will hang the system, most notably
1898 * with VIO sessions. I have been unable to figure
1899 * out why this happens, so XWorkplace now uses
1900 * its daemon to call WinStartApp instead.
1901 *
1902 * As a word of wisdom, do not call this from
1903 * within the Workplace process. For some strange
1904 * reason though, the XWorkplace "Run" dialog
1905 * (which uses this) _does_ work. Whatever.
