1161 * -- As with WinStartApp, if PROGDETAILS.pszEnvironment
1162 * is NULL, the new app inherits a default environment
1163 * from the shell.
1164 *
1165 * -- However, if you specify an environment, you _must_
1166 * specify a complete environment. This function
1167 * will not merge environments. Use
1168 * appSetEnvironmentVar to change environment
1169 * variables in a complete environment set.
1170 *
1171 * -- If PROGDETAILS specifies a Win-OS/2 session
1172 * and PROGDETAILS.pszEnvironment is empty,
1173 * this uses the default Win-OS/2 environment.
1174 * See appQueryDefaultWin31Environment.
1175 *
1176 * Even though this isn't clearly said in PMREF,
1177 * PROGDETAILS.swpInitial is important:
1178 *
1179 * -- To start a session minimized, set SWP_MINIMIZE.
1180 *
1181 * -- To start a VIO session with auto-close disabled,
1182 * set the half-documented SWP_NOAUTOCLOSE flag (0x8000)
1183 * This flag is now in the newer toolkit headers.
1184 *
1185 * In addition, this supports the following session
1186 * flags with ulFlags if PROG_DEFAULT is specified:
1187 *
1188 * -- APP_RUN_FULLSCREEN
1189 *
1190 * -- APP_RUN_ENHANCED
1191 *
1192 * -- APP_RUN_STANDARD
1193 *
1194 * -- APP_RUN_SEPARATE
1195 *
1196 * Since this calls WinStartApp in turn, this
1197 * requires a message queue on the calling thread.
1198 *
1199 * Note that this also does minimal checking on
1200 * the specified parameters so it can return something
1201 * more meaningful than FALSE like WinStartApp.
1202 * As a result, you get a DOS error code now (V0.9.16).
1203 *
1204 * Most importantly:
1205 *
1206 * -- ERROR_INVALID_THREADID: not running on thread 1.
1207 * Since this uses WinStartApp internally and
1208 * WinStartApp completely hangs the session manager
1209 * if a Win-OS/2 full-screen session is started from
1210 * a thread that is NOT thread 1, this will now fail
1211 * with this error for safety (V0.9.16).
1212 *
1213 * -- ERROR_INVALID_PARAMETER: pcProgDetails or
1214 * phapp is NULL; or PROGDETAILS.pszExecutable is NULL.
1215 *
1216 * -- ERROR_FILE_NOT_FOUND, ERROR_PATH_NOT_FOUND:
1217 * PROGDETAILS.pszExecutable and/or PROGDETAILS.pszStartupDir
1218 * are invalid.
1219 * A NULL PROGDETAILS.pszStartupDir is supported though.
1220 *
1221 * -- ERROR_NOT_ENOUGH_MEMORY
