By default, ten lines are printed. +There are several ways to specify what part of the file you want to +print; see <a href="Location-Specifications.html#Location-Specifications">Location Specifications</a>, for the full list. +</p> +<p>Here are the forms of the <code>list</code> command most commonly used: +</p> +<dl compact="compact"> +<dt><code>list <var>linenum</var></code></dt> +<dd><p>Print lines centered around line number <var>linenum</var> in the +current source file. +</p> +</dd> +<dt><code>list <var>function</var></code></dt> +<dd><p>Print lines centered around the beginning of function +<var>function</var>. +</p> +</dd> +<dt><code>list</code></dt> +<dd><p>Print more lines. If the last lines printed were printed with a +<code>list</code> command, this prints lines following the last lines +printed; however, if the last line printed was a solitary line printed +as part of displaying a stack frame (see <a href="Stack.html#Stack">Examining the +Stack</a>), this prints lines centered around that line. +</p> +</dd> +<dt><code>list -</code></dt> +<dd><p>Print lines just before the lines last printed. +</p></dd> +</dl> + +<a name="index-list_002c-how-many-lines-to-display"></a> +<p>By default, <small>GDB</small> prints ten source lines with any of these forms of +the <code>list</code> command.

This is more useful +than listing the same lines again. An exception is made for an +argument of ‘<samp>-</samp>’; that argument is preserved in repetition so that +each repetition moves up in the source file. +</p> +<p>In general, the <code>list</code> command expects you to supply zero, one or +two location specs. These location specs are interpreted to resolve +to source code lines; there are several ways of writing them +(see <a href="Location-Specifications.html#Location-Specifications">Location Specifications</a>), but the effect is always to resolve +to some source lines to display. +</p> +<p>Here is a complete description of the possible arguments for <code>list</code>: +</p> +<dl compact="compact"> +<dt><code>list <var>locspec</var></code></dt> +<dd><p>Print lines centered around the line or lines of all the code +locations that result from resolving <var>locspec</var>. +</p> +</dd> +<dt><code>list <var>first</var>,<var>last</var></code></dt> +<dd><p>Print lines from <var>first</var> to <var>last</var>. Both arguments are +location specs. When a <code>list</code> command has two location specs, +and the source file of the second location spec is omitted, this +refers to the same source file as the first location spec. If either +<var>first</var> or <var>last</var> resolve to more than one source line in the +program, then the list command shows the list of resolved source +lines and does not proceed with the source code listing. +</p> +</dd> +<dt><code>list ,<var>last</var></code></dt> +<dd><p>Print lines ending with <var>last</var>. +</p> +<p>Likewise, if <var>last</var> resolves to more than one source line in the +program, then the list command prints the list of resolved source +lines and does not proceed with the source code listing. +</p> +</dd> +<dt><code>list <var>first</var>,</code></dt> +<dd><p>Print lines starting with <var>first</var>. +</p> +</dd> +<dt><code>list +</code></dt> +<dd><p>Print lines just after the lines last printed. +</p> +</dd> +<dt><code>list -</code></dt> +<dd><p>Print lines just before the lines last printed. +</p> +</dd> +<dt><code>list</code></dt> +<dd><p>As described in the preceding table. +</p></dd> +</dl> + +<hr> +<div class="header"> +<p> +Next: <a href="Location-Specifications.html#Location-Specifications" accesskey="n" rel="next">Location Specifications</a>, Up: <a href="Source.html#Source" accesskey="u" rel="up">Source</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> |
