<p>
Matches a string against a compiled pattern. Passing the correct length of the
string given is mandatory. The reversed string can be omitted by passing <code class="literal">NULL</code>,
this is more efficient if the reversed version of the string to be matched is
not at hand, as <a href="glib-Glob-style-pattern-matching.html#g-pattern-match"><code class="function">g_pattern_match()</code></a> will only construct it if the compiled pattern
requires reverse matches.
</p>
<p>
Note that, if the user code will (possibly) match a string against a multitude 
of patterns containing wildcards, chances are high that some patterns will 
require a reversed string. In this case, it's more efficient to provide the 
reversed string to avoid multiple constructions thereof in the various calls to
<a href="glib-Glob-style-pattern-matching.html#g-pattern-match"><code class="function">g_pattern_match()</code></a>.
</p>
<p>
Note also that the reverse of a UTF-8 encoded string can in general 
<span class="emphasis"><em>not</em></span> be obtained by <a href="glib-String-Utility-Functions.html#g-strreverse"><code class="function">g_strreverse()</code></a>.
This works only if the string doesn't contain any multibyte characters.
Glib offers the <code class="function">g_utf_strreverse()</code> function to reverse UTF-8 encoded strings.
