| Format strings are used by the algorithm <a class="link" href="ref/regex_replace.html" title="regex_replace"><code class="computeroutput"><span class="identifier">regex_replace</span></code></a> and by <a class="link" href="ref/match_results.html#boost_regex.match_results_format"><code class="computeroutput"><span class="identifier">match_results</span><span class="special"><>::</span><span class="identifier">format</span></code></a>, and are used to transform |
| one string into another. |
| </p> |
| <p> |
| There are three kind of format string: <a class="link" href="format/sed_format.html" title="Sed Format String Syntax">Sed</a>, |
| <a class="link" href="format/perl_format.html" title="Perl Format String Syntax">Perl</a> and <a class="link" href="format/boost_format_syntax.html" title="Boost-Extended Format String Syntax">Boost-Extended</a>. |
| </p> |
| <p> |
| Alternatively, when the flag <code class="computeroutput"><span class="identifier">format_literal</span></code> |
| is passed to one of these functions, then the format string is treated as a |
| string literal, and is copied unchanged to the output. |
