-<h4>Description</h4>\r
-<p>After the directory specified by <tt class="arg">path</tt> could be opened, it starts to search the directory for items with the name specified by <tt class="arg">pattern</tt>. If the first item is found, the information about the object is stored into the file information structure. For more information about file information structure, refer to <a href="readdir.html"><tt>f_readdir</tt></a> function.</p>\r
-<p>The matching pattern can contain wildcard characters (<tt>?</tt> and <tt>*</tt>). A <tt>?</tt> matches an any character and an <tt>*</tt> matches an any string in length of zero or longer. When support of long file name is enabled, only <tt>fname[]</tt> is tested at <tt>_USE_FIND == 1</tt> and also <tt>altname[]</tt> is tested at <tt>_USE_FIND == 2</tt>. In this revision, there are some differences listed below between FatFs and standard systems in matching condition.</p>\r
-<ul>\r
-<li><tt>"*.*"</tt> never matches any name without extension while it matches any name with or without extension at the standard systems.</li>\r
-<li>Any patterns terminated with a period never matches any name while it matches any name without extensiton at the standard systems.</li>\r
-<li><a href="filename.html#case">DBCS extended characters</a> are compared in case-sensitive at LFN with non-Unicode configuration.</li>\r
