<H3><a name="Cpp0x_User_defined_literals"></a>7.2.19 User-defined literals</H3>
<p>SWIG correctly parses the new <tt>operator""_mysuffix()</tt> functions.</p>
<p>
SWIG parses the declaration of user-defined literals, that is, the <tt>operator "" _mysuffix()</tt> function syntax.
</p>
<p>
Some examples are the raw literal:
</p>
<div class="code"><pre>
OutputType operator "" _myRawLiteral(const char * value);
</pre></div>
<p>
numeric cooked literals:
</p>
<div class="code"><pre>
OutputType operator "" _mySuffixIntegral(unsigned long long);
OutputType operator "" _mySuffixFloat(long double);
</pre></div>
<p>
and cooked string literals:
</p>
<div class="code"><pre>
OutputType operator "" _mySuffix(const char * string_values, size_t num_chars);
OutputType operator "" _mySuffix(const wchar_t * string_values, size_t num_chars);
OutputType operator "" _mySuffix(const char16_t * string_values, size_t num_chars);
OutputType operator "" _mySuffix(const char32_t * string_values, size_t num_chars);
OutputType operator "" _mySuffix(int value);
</pre></div>
<p>The %rename currently doesn't parse the double quotes. Please
rename the functions in the code using the #define preprocessor directive.</p>
<p>
Note that the %rename directive currently does not parse the double quotes, so these can't be easily accessed from
target languages.
</p>
<p>
Use of user-defined literals such as the following still give a syntax error:
</p>
<div class="code"><pre>
OutputType var1 = "1234"_suffix;
OutputType var2 = 1234_suffix;
OutputType var3 = 3.1416_suffix;
</pre></div>
