<H3>BOOST_BITWISE_EQUAL( left, right )</H3>
<P class="first-line-indented">This tool is used to perform bitwise comparison of two values. This check
shows all positions where <I>left</I> and <I>right</I> value's bits mismatch.</P>
<P class="first-line-indented">If comparisons are successful, the tool produces a confirmation messages
(note: to manage what messages appear in the test output stream set the proper log level), in other
case in every mismatch position it produces an error message in a form &quot;error in &lt;test case
name&gt;: test &lt;<I>left</I>&gt; =.= &lt;<I>right</I>&gt; in a position &lt;<I>mismatch position</I>&gt;
failed.</P>
<P class="first-line-indented">The tool's first parameter is the <I>left</I> compared value. Second
parameter is the <I>right</I> compared value. Parameters are not required to be of the same type,
but warning is issues if their size does not coincide.</P>
<H4>Example: test.cpp</H4>
<PRE class="code"><SPAN class="cpp-type">int</SPAN> test_main( <SPAN class="cpp-type">int</SPAN>, <SPAN class="cpp-type">char</SPAN>* [] ) {
BOOST_BITWISE_EQUAL( (<SPAN class="cpp-type">char</SPAN>)<SPAN class="literal">0x26</SPAN>, (<SPAN class="cpp-type">char</SPAN>)<SPAN class="literal">0x04</SPAN> );
<SPAN class="reserv-word">return</SPAN> <SPAN class="literal">0</SPAN>;
}</PRE>
<H4>Output:</H4>
<P class="test-output">test.cpp(3) : error in test_main: test (char)0x26 =.= (char)0x04 in the position 1 failed<BR>
test.cpp(3) : error in test_main: test (char)0x26 =.= (char)0x04 in the position 5 failed</P>
