<title>Description</title>

<para><command>Valgrind</command> is a flexible program for debugging
and profiling Linux executables.  It consists of a core, which provides
a synthetic CPU in software, and a series of "tools", each of which is a
debugging or profiling tool. The architecture is modular, so that new
tools can be created easily and without disturbing the existing
structure.</para>

<para>This manual page covers only basic usage and options.  For more
comprehensive information, please see the HTML documentation on your
system: <filename>&vg-doc-path;</filename>, or online:
<filename>&vg-bookset;</filename>.</para>

<refsect1 id="invocation">
<title>Invocation</title>

<para><command>Valgrind</command> is typically invoked as follows:
<literallayout>    valgrind program args</literallayout>

This runs <command>program</command> (with arguments
<command>args</command>) under Valgrind using the Memcheck tool.
Memcheck performs a range of memory-checking functions, including
detecting accesses to uninitialised memory, misuse of allocated memory
(double frees, access after free, etc.) and detecting memory
leaks.</para>

<para>To use a different tool, use the <option>--tool</option> option:
<literallayout>    valgrind --tool=toolname program args</literallayout></para>

<para>The following tools are available:</para>

<itemizedlist>

  <listitem>
    <para><option>cachegrind</option> is a cache simulator.  It can be
    used to annotate every line of your program with the number of
    instructions executed and cache misses incurred.</para>
  </listitem>

  <listitem>
    <para><option>helgrind</option> spots potential race conditions in
    your program.</para>
  </listitem>

  <listitem>
    <para><option>lackey</option> is a sample tool that can be used as a
    template for generating your own tools. After the program
    terminates, it prints out some basic statistics about the program
    execution.</para>
  </listitem>

  <listitem>
    <para><option>massif</option> is a heap profiler.  It measures how
    much heap memory your program uses.</para>
  </listitem>

  <listitem>
    <para><option>memcheck</option> is a fine-grained memory checker.</para>
  </listitem>

  <listitem>
    <para><option>none</option> performs no function - it simply runs
    the program under Valgrind.  This is typically used for debugging
    and benchmarking Valgrind.</para>
  </listitem>
