<h2>FIL</h2>
|
|
<p>The FIL structure (file object) holds state of an open file. It is created by f_open function and discarded by f_close function. There is no member that can be changed by the application program except for <tt>cltbl</tt>. Note that a sector buffer is defined in this structure under non-tiny configuration so that the FIL structures should not be defined as auto variable.</p>
