Each command results in exactly one response, +indicating either successful completion of the command, or an error. +For the commands that do not resume the target, the response contains the +requested information. For the commands that resume the target, the +response only indicates whether the target was successfully resumed. +Notifications is the mechanism for reporting changes in the state of the +target, or in <small>GDB</small> state, that cannot conveniently be associated with +a command and reported as part of that command response. +</p> +<p>The important examples of notifications are: +</p><ul> +<li> Exec notifications. These are used to report changes in +target state—when a target is resumed, or stopped. It would not +be feasible to include this information in response of resuming +commands, because one resume commands can result in multiple events in +different threads. Also, quite some time may pass before any event +happens in the target, while a frontend needs to know whether the resuming +command itself was successfully executed. + +</li><li> Console output, and status notifications. Console output +notifications are used to report output of CLI commands, as well as +diagnostics for other commands. Status notifications are used to +report the progress of a long-running operation. Naturally, including +this information in command response would mean no output is produced +until the command is finished, which is undesirable. + +</li><li> General notifications. Commands may have various side effects on +the <small>GDB</small> or target state beyond their official purpose. For example, +a command may change the selected thread. Although such changes can +be included in command response, using notification allows for more +orthogonal frontend design. + +</li></ul> + +<p>There’s no guarantee that whenever an MI command reports an error, +<small>GDB</small> or the target are in any specific state, and especially, +the state is not reverted to the state before the MI command was +processed. Therefore, whenever an MI command results in an error, +we recommend that the frontend refreshes all the information shown in +the user interface. +</p> + +<table class="menu" border="0" cellspacing="0"> +<tr><td align="left" valign="top">• <a href="Context-management.html#Context-management" accesskey="1">Context management</a>:</td><td> </td><td align="left" valign="top"> +</td></tr> +<tr><td align="left" valign="top">• <a href="Asynchronous-and-non_002dstop-modes.html#Asynchronous-and-non_002dstop-modes" accesskey="2">Asynchronous and non-stop modes</a>:</td><td> </td><td align="left" valign="top"> +</td></tr> +<tr><td align="left" valign="top">• <a href="Thread-groups.html#Thread-groups" accesskey="3">Thread groups</a>:</td><td> </td><td align="left" valign="top"> +</td></tr> +</table> + +<hr> +<div class="header"> +<p> +Next: <a href="GDB_002fMI-Command-Syntax.html#GDB_002fMI-Command-Syntax" accesskey="n" rel="next">GDB/MI Command Syntax</a>, Up: <a href="GDB_002fMI.html#GDB_002fMI" accesskey="u" rel="up">GDB/MI</a> [<a href="index.html#SEC_Contents" title="Table of contents" rel="contents">Contents</a>][<a href="Concept-Index.html#Concept-Index" title="Index" rel="index">Index</a>]</p> +</div> + + + +</body> +</html> |
