1163 * environments for the app to be started. The
1164 * following should be respected:
1165 *
1166 * -- As with WinStartApp, if PROGDETAILS.pszEnvironment
1167 * is NULL, the new app inherits a default environment
1168 * from the shell.
1169 *
1170 * -- However, if you specify an environment, you _must_
1171 * specify a complete environment. This function
1172 * will not merge environments. Use
1173 * appSetEnvironmentVar to change environment
1174 * variables in a complete environment set.
1175 *
1176 * -- If PROGDETAILS specifies a Win-OS/2 session
1177 * and PROGDETAILS.pszEnvironment is empty,
1178 * this uses the default Win-OS/2 environment.
1179 * See appQueryDefaultWin31Environment.
1180 *
1181 * Even though this isn't clearly said in PMREF,
1182 * PROGDETAILS.swpInitial is important:
1183 *
1184 * -- To start a session minimized, set SWP_MINIMIZE.
1185 *
1186 * -- To start a VIO session with auto-close disabled,
1187 * set the half-documented SWP_NOAUTOCLOSE flag (0x8000)
1188 * This flag is now in the newer toolkit headers.
1189 *
1190 * In addition, this supports the following session
1191 * flags with ulFlags if PROG_DEFAULT is specified:
1192 *
1193 * -- APP_RUN_FULLSCREEN
1194 *
1195 * -- APP_RUN_ENHANCED
1196 *
1197 * -- APP_RUN_STANDARD
1198 *
1199 * -- APP_RUN_SEPARATE
1200 *
1201 * Since this calls WinStartApp in turn, this
1202 * requires a message queue on the calling thread.
1203 *
1204 * Note that this also does minimal checking on
1205 * the specified parameters so it can return something
1206 * more meaningful than FALSE like WinStartApp.
1207 * As a result, you get a DOS error code now (V0.9.16).
1208 *
1209 * Most importantly:
1210 *
1211 * -- ERROR_INVALID_THREADID: not running on thread 1.
1212 * Since this uses WinStartApp internally and
1213 * WinStartApp completely hangs the session manager
1214 * if a Win-OS/2 full-screen session is started from
1215 * a thread that is NOT thread 1, this will now fail
1216 * with this error for safety (V0.9.16).
1217 *
1218 * -- ERROR_INVALID_PARAMETER: pcProgDetails or
1219 * phapp is NULL; or PROGDETAILS.pszExecutable is NULL.
1220 *
1221 * -- ERROR_FILE_NOT_FOUND, ERROR_PATH_NOT_FOUND:
1222 * PROGDETAILS.pszExecutable and/or PROGDETAILS.pszStartupDir
1223 * are invalid.
1224 * A NULL PROGDETAILS.pszStartupDir is supported though.
1225 *
1226 * -- ERROR_NOT_ENOUGH_MEMORY
