<p>
The header <STRONG>&lt;boost/assert.hpp&gt;</STRONG> defines the macro <b>BOOST_ASSERT</b>,
which is similar to the standard <STRONG>assert</STRONG> macro defined in <STRONG>&lt;cassert&gt;</STRONG>.
The macro is intended to be used in both Boost libraries and user
code.

<P>If the macro <STRONG>BOOST_DISABLE_ASSERTS</STRONG> is defined when <STRONG>&lt;boost/assert.hpp&gt;</STRONG>
is included, <tt>BOOST_ASSERT(expr)</tt> is defined as <tt>((void)0)</tt>. This
allows users to selectively disable <STRONG>BOOST_ASSERT</STRONG> without
affecting the definition of the standard <STRONG>assert</STRONG>.</P>
<P>If the macro <STRONG>BOOST_ENABLE_ASSERT_HANDLER</STRONG> is defined when <STRONG>&lt;boost/assert.hpp&gt;</STRONG>
is included, <tt>BOOST_ASSERT(expr)</tt> evaluates <b>expr</b> and, if the
result is false, evaluates the expression</P>

<h2><a name="BOOST_ASSERT_MSG">BOOST_ASSERT_MSG</a></h2>
<p>
The header <STRONG>&lt;boost/assert.hpp&gt;</STRONG> defines the macro <b>BOOST_ASSERT_MSG</b>,
which is similar to the standard <STRONG>assert</STRONG> macro defined in <STRONG>&lt;cassert&gt;</STRONG>,
but with an additional macro parameter supplying an error message. The macro is intended to be used in both Boost libraries
and user code.
</p>
<P> <tt>BOOST_ASSERT_MSG(expr, msg)</tt> is equivalent to <code>
((void)0)</code> if <b>BOOST_DISABLE_ASSERTS</b> or <b>NDEBUG</b> are
defined or <code>expr</code> evaluates to <code>true</code>. If those
macros and <STRONG>BOOST_ENABLE_ASSERT_HANDLER</STRONG> are not
defined, and <code>expr</code> evaluates to <code>false</code>, an error
message that includes <tt>#expr</tt>, <tt>msg</tt>, <tt> <a href="current_function.html">BOOST_CURRENT_FUNCTION</a></tt>, <tt>
__FILE__</tt>, and <tt>__LINE__</tt> is sent to output stream <b>
BOOST_ASSERT_MSG_OSTREAM</b>
and <code>std::abort()</code> is called.</P>
<P> <b>BOOST_ASSERT_MSG_OSTREAM</b> defines the output stream. It defaults to <code>std::cerr</code>.
Integrated development environments (IDE's) like Microsoft Visual Studio
may produce easier to understand output if messages go to a different
stream, such as <code>std::cout</code>. Users may define <b>BOOST_ASSERT_MSG_OSTREAM</b> before including <STRONG>&lt;boost/assert.hpp&gt;</STRONG>
to specify a different output stream.&nbsp; </P>
<P>If the macro <STRONG>BOOST_ENABLE_ASSERT_HANDLER</STRONG> is defined when <STRONG>&lt;boost/assert.hpp&gt;</STRONG>
is included, instead of sending a error message to an output
stream, this expression is evaluated</P>
<blockquote>
<P><tt>::boost::assertion_failed_msg(#expr, msg, <a href="current_function.html">BOOST_CURRENT_FUNCTION</a>,
__FILE__, __LINE__)</tt></P>
</blockquote>
<P><STRONG>assertion_failed_msg</STRONG> is declared in <STRONG>&lt;boost/assert.hpp&gt;</STRONG>
as</P>
<blockquote>
<pre>namespace boost
{
void assertion_failed_msg(char const * expr, char const * msg, char const * function, char const * file, long line);
}
</pre>

<p>but it is never defined. The user is expected to supply an appropriate
definition.</p>
<P>As is the case with <STRONG>&lt;cassert&gt;</STRONG>, <STRONG>&lt;boost/assert.hpp&gt;</STRONG>
can be included multiple times in a single translation unit. <STRONG>BOOST_ASSERT_MSG</STRONG>
will be redefined each time as specified above.</P>
<h2><a name="BOOST_VERIFY">BOOST_VERIFY</a></h2>
<p><STRONG>&lt;boost/assert.hpp&gt;</STRONG> also defines the macro <STRONG>BOOST_VERIFY</STRONG>.
It has exactly the same behavior as <STRONG>BOOST_ASSERT</STRONG>, except that
the expression that is passed to <STRONG>BOOST_VERIFY</STRONG> is always
evaluated. This is useful when the asserted expression has desirable side
effects; it can also help suppress warnings about unused variables when the
only use of the variable is inside an assertion.</p>

The header <STRONG>&lt;boost/current_function.hpp&gt;</STRONG> defines a single
macro, <STRONG>BOOST_CURRENT_FUNCTION</STRONG>,<STRONG> </STRONG>similar to the
C99 predefined identifier <STRONG>__func__</STRONG>.
</p>
<P><STRONG>BOOST_CURRENT_FUNCTION</STRONG> expands to a string literal containing
the (fully qualified, if possible) name of the enclosing function. If there is
no enclosing function, the behavior is undefined.</P>
<p>Some compilers do not provide a way to obtain the name of the current enclosing
function. On such compilers, the string literal has an unspecified value.</p>
