+<p>Note that on compilers that support variadic macros (most of moder compliers and all C++11 compilers), the capture list can be specified as a comma-separated list of tokens (this is the preferred syntax). However, on all compilers the same macro <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT.html" title="Macro BOOST_SCOPE_EXIT">BOOST_SCOPE_EXIT</a></code> also allows to specify the capture list as a Boost.Preprocessor sequence of tokens (for supporting compilers without variadic macros and for backward compatibility with older versions of this library).</p>
+<p>The name <code class="computeroutput">variable</code> of each captured variable must be a valid name in the enclosing scope and it must appear exactly once in the capture list. If a capture starts with the ampersand sign <code class="computeroutput">&</code>, the corresponding variable will be available by reference within the scope exit body; otherwise, a copy of the variable will be made at the point of the scope exit declaration and that copy will be available inside the scope exit body (in this case, the variable's type must be <code class="computeroutput">CopyConstructible</code>).</p>
+<p>From within a member function, the object <code class="computeroutput">this</code> can be captured using the special name <code class="computeroutput">this_</code> in both the capture list and the scope exit body (using <code class="computeroutput">this</code> instead of <code class="computeroutput">this_</code> in the scope exit body leads to undefined behaviour).</p>
+<p>It is possible to capture no variable by specifying the capture list as <code class="computeroutput">void</code> (regardless of variadic macro support).</p>
+<p>Only variables listed in the capture list, static variables, <code class="computeroutput">extern</code> variables, global variables, functions, and enumerations from the enclosing scope can be used inside the scope exit body.</p>
+<p>On various GCC versions the special macro <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT_TPL.html" title="Macro BOOST_SCOPE_EXIT_TPL">BOOST_SCOPE_EXIT_TPL</a></code> must be used instead of <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT.html" title="Macro BOOST_SCOPE_EXIT">BOOST_SCOPE_EXIT</a></code> within templates (to maximize portability, it is recommended to always use <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT_TPL.html" title="Macro BOOST_SCOPE_EXIT_TPL">BOOST_SCOPE_EXIT_TPL</a></code> within templates).</p>
+<p>On C++11, it is possible capture all variables in scope without listing their names one-by-one using the macro <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT_ALL.html" title="Macro BOOST_SCOPE_EXIT_ALL">BOOST_SCOPE_EXIT_ALL</a></code>.</p>
+<p>In general, the special macro <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT_ID.html" title="Macro BOOST_SCOPE_EXIT_ID">BOOST_SCOPE_EXIT_ID</a></code> must be used instead of <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT.html" title="Macro BOOST_SCOPE_EXIT">BOOST_SCOPE_EXIT</a></code> when it is necessary to expand multiple scope exit declarations on the same line.</p>

+<p>Various versions of the GCC compiler do not compile <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT.html" title="Macro BOOST_SCOPE_EXIT">BOOST_SCOPE_EXIT</a></code> inside function templates. As a workaround, <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT_TPL.html" title="Macro BOOST_SCOPE_EXIT_TPL">BOOST_SCOPE_EXIT_TPL</a></code> should be used instead of <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT.html" title="Macro BOOST_SCOPE_EXIT">BOOST_SCOPE_EXIT</a></code> in these cases:</p>
+<pre class="programlisting"> <span class="special">{</span> <span class="comment">// Some local scope.</span>

+ <span class="identifier">BOOST_SCOPE_EXIT_TPL</span><span class="special">(</span><span class="identifier">capture_list</span><span class="special">)</span> <span class="special">{</span>

+ <span class="special">}</span> <span class="identifier">BOOST_SCOPE_EXIT_END</span>
+ <span class="special">...</span>
+ <span class="special">}</span>
+</pre>
+<p>The syntax of <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT_TPL.html" title="Macro BOOST_SCOPE_EXIT_TPL">BOOST_SCOPE_EXIT_TPL</a></code> is the exact same as the one of <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT.html" title="Macro BOOST_SCOPE_EXIT">BOOST_SCOPE_EXIT</a></code> (see <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT.html" title="Macro BOOST_SCOPE_EXIT">BOOST_SCOPE_EXIT</a></code> for more information).</p>
+<p>On C++11 compilers, <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT_TPL.html" title="Macro BOOST_SCOPE_EXIT_TPL">BOOST_SCOPE_EXIT_TPL</a></code> is not needed because <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT.html" title="Macro BOOST_SCOPE_EXIT">BOOST_SCOPE_EXIT</a></code> always compiles on GCC versions that support C++11. However, <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT_TPL.html" title="Macro BOOST_SCOPE_EXIT_TPL">BOOST_SCOPE_EXIT_TPL</a></code> is still provided on C++11 so to write code that is portable between C++03 and C++11 compilers. It is recommended to always use <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT_TPL.html" title="Macro BOOST_SCOPE_EXIT_TPL">BOOST_SCOPE_EXIT_TPL</a></code> within templates so to maximize portability.</p>
+<p>In general, the special macro <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT_ID_TPL.html" title="Macro BOOST_SCOPE_EXIT_ID_TPL">BOOST_SCOPE_EXIT_ID_TPL</a></code> must be used instead of <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT_TPL.html" title="Macro BOOST_SCOPE_EXIT_TPL">BOOST_SCOPE_EXIT_TPL</a></code> when it is necessary to expand multiple scope exit declarations on the same line within templates.</p>
+<p><span class="bold"><strong>Note:</strong></span> The issue in compiling scope exit declarations that some GCC versions have is illustrated by the following code (see also GCC bug 37920): </p>

+ Nowadays, every C++ developer is familiar with the Resource Acquisition Is
+ Initialization (RAII)
+ technique. It binds resource acquisition and release to initialization and
+ destruction of a variable that holds the resource. There are times when writing
+ a special class for such a variable is not worth the effort. This is when
+ <a class="link" href="index.html" title="Chapter 1. Boost.ScopeExit 1.1.0">Boost.ScopeExit</a> comes into play.
+ </p>
+<p>
+ Programmers can put resource acquisition directly in their code and next to
+ it, they can write code that releases the resource using this library. For
+ example (see also world.cpp
):

+ RAII

+ This library is composed of header files only. Therefore there is no pre-compiled

+<p>
+ The library implementation uses Boost.Typeof

+ captured variables (see the <a class="link" href="tutorial.html" title="Tutorial">Tutorial</a>

+ Most modern compilers support variadic macros (notably, these include GCC,

+ sequence where tokens are separated by round parenthesis <code class="computeroutput"><span class="special">()</span></code>:
+ </p>
+<pre class="programlisting"><span class="special">(</span><span class="identifier">capture1</span><span class="special">)</span> <span class="special">(</span><span class="identifier">capture2</span><span class="special">)</span> <span class="special">...</span> <span class="comment">// All compilers.</span>

+ Imagine that we want to make many modifications to data members of some
+ <code class="computeroutput"><span class="identifier">world</span></code> class in its <code class="computeroutput"><span class="identifier">world</span><span class="special">::</span><span class="identifier">add_person</span></code> member function. We start with
+ adding a new <code class="computeroutput"><span class="identifier">person</span></code> object
+ to a vector of persons:
+ </p>
+<pre class="programlisting"><span class="keyword">void</span> <span class="identifier">world</span><span class="special">::</span><span class="identifier">add_person</span><span class="special">(</span><span class="identifier">person</span> <span class="keyword">const</span><span class="special">&</span> <span class="identifier">a_person</span><span class="special">)</span> <span class="special">{</span>

+ guarantee</a>.
+ </p>
+<p>
+ In particular, the last added person must be deleted from <code class="computeroutput"><span class="identifier">persons_</span></code>
+ if the function throws. All we need is to define a delayed action (release
+ of a resource) right after the direct action (resource acquisition). For

+<p>
+ </p>
+<p>
+ The block below point <code class="literal">(1)</code> is a <a class="link" href="../index.html" title="Chapter 1. Boost.ScopeExit 1.1.0">Boost.ScopeExit</a>
+ declaration. Unlike point <code class="literal">(1)</code>, an execution of the <a class="link" href="../index.html" title="Chapter 1. Boost.ScopeExit 1.1.0">Boost.ScopeExit</a> body will be delayed until the
+ end of the current scope. In this case it will be executed either after point
+ <code class="literal">(4)</code> or on any exception. (On various versions of the GCC
+ compiler, it is necessary to use <code class="computeroutput"><a class="link" href="../BOOST_SCOPE_EXIT_TPL.html" title="Macro BOOST_SCOPE_EXIT_TPL">BOOST_SCOPE_EXIT_TPL</a></code>
+ instead of <code class="computeroutput"><a class="link" href="../BOOST_SCOPE_EXIT.html" title="Macro BOOST_SCOPE_EXIT">BOOST_SCOPE_EXIT</a></code>
+ within templates, see later in this section for details.)
+ </p>
+<p>
+ The <a class="link" href="../index.html" title="Chapter 1. Boost.ScopeExit 1.1.0">Boost.ScopeExit</a> declaration starts
+ with the <code class="computeroutput"><a class="link" href="../BOOST_SCOPE_EXIT.html" title="Macro BOOST_SCOPE_EXIT">BOOST_SCOPE_EXIT</a></code> macro
+ invocation which accepts a comma-separated list of captured variables (a
+ Boost.Preprocessor
+ sequence is also accepted for compilers that do not support variadic macros
+ and for backward compatibility with older versions of this library, see the
+ <a class="link" href="no_variadic_macros.html" title="Annex: No Variadic Macros">No Variadic Macros</a> section).
+ If a capture starts with the ampersand sign <code class="computeroutput"><span class="special">&</span></code>,
+ a reference to the captured variable will be available inside the <a class="link" href="../index.html" title="Chapter 1. Boost.ScopeExit 1.1.0">Boost.ScopeExit</a>
+ body; otherwise, a copy of the variable will be made after the <a class="link" href="../index.html" title="Chapter 1. Boost.ScopeExit 1.1.0">Boost.ScopeExit</a>
+ declaration at point <code class="literal">(1)</code> and only the copy will be available
+ inside the body (in this case, the captured variable's type must be CopyConstructible
).
+ </p>
+<p>
+ In the example above, the variables <code class="computeroutput"><span class="identifier">commit</span></code>
+ and <code class="computeroutput"><span class="identifier">persons_</span></code> are captured
+ by reference because the final value of the <code class="computeroutput"><span class="identifier">commit</span></code>
+ variable should be used to determine whether to execute rollback actions
+ or not, and the action should modify the <code class="computeroutput"><span class="identifier">persons_</span></code>
+ object, not its copy. This is the most common case but passing a variable
+ by value is sometimes useful as well.
+ </p>
+<p>
+ Finally, the end of the <a class="link" href="../index.html" title="Chapter 1. Boost.ScopeExit 1.1.0">Boost.ScopeExit</a>
+ body must be marked by the <code class="computeroutput"><a class="link" href="../BOOST_SCOPE_EXIT_END.html" title="Macro BOOST_SCOPE_EXIT_END">BOOST_SCOPE_EXIT_END</a></code>
+ macro which must follow the closing curly bracket <code class="computeroutput"><span class="special">}</span></code>
+ of the <a class="link" href="../index.html" title="Chapter 1. Boost.ScopeExit 1.1.0">Boost.ScopeExit</a> body.

+ Consider a more complex example where <code class="computeroutput"><span class="identifier">world</span><span class="special">::</span><span class="identifier">add_person</span></code>
+ can save intermediate states at some point and roll back to the last saved

+ and increment it to cancel all rollback actions associated with those changes.
+ If we pass a current value of <code class="computeroutput"><span class="identifier">evolution_</span></code>
+ stored in the <code class="computeroutput"><span class="identifier">checkpoint</span></code>
+ variable by value, it remains unchanged within the <a class="link" href="../index.html" title="Chapter 1. Boost.ScopeExit 1.1.0">Boost.ScopeExit</a>
+ body so we can compare it with the final value of <code class="computeroutput"><span class="identifier">evolution_</span></code>.
+ If the latter was not incremented since we saved it, the rollback action
+ inside the <a class="link" href="../index.html" title="Chapter 1. Boost.ScopeExit 1.1.0">Boost.ScopeExit</a> body should

+<p>
+ On C++11 compliers, it is also possible to capture all the variables in scope
+ without naming them one-by-one using the special macro <code class="computeroutput"><a class="link" href="../BOOST_SCOPE_EXIT_ALL.html" title="Macro BOOST_SCOPE_EXIT_ALL">BOOST_SCOPE_EXIT_ALL</a></code>

+<p>
+ Following the same syntax adopted by C++11 lambda functions, the <code class="computeroutput"><a class="link" href="../BOOST_SCOPE_EXIT_ALL.html" title="Macro BOOST_SCOPE_EXIT_ALL">BOOST_SCOPE_EXIT_ALL</a></code> macro accepts
+ a comma-separated list of captures which must start with either <code class="computeroutput"><span class="special">&</span></code> or <code class="computeroutput"><span class="special">=</span></code>
+ to capture all variables in scope respectively by reference or by value (note
+ that no variable name is specified by these leading captures). Additional
+ captures of specific variables can follow the leading <code class="computeroutput"><span class="special">&</span></code>
+ or <code class="computeroutput"><span class="special">=</span></code> and they will override
+ the default reference or value captures. For example (see also world_checkpoint_all.cpp
