<p>After the directory specified by <tt class="arg">path</tt> could be opened, it starts to search the directory for the item with a name specified by <tt class="arg">pattern</tt>. If found, the information about the object is stored into the file information structure.

<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. At LFN configuration, both names of the item, SFN and LFN (if exist), are tested. In this revision, there are some differences listed below between FatFs and standard systems in matching condition.</p>
