<h4>Description</h4>
|
|
<p>The f_mount function registers/unregisters a work area to the FatFs module. The work area must be given to the each volume with this function prior to use any other file function. To unregister a work area, specify a NULL to the <em>FileSystemObject</em>, and then the work area can be discarded.</p>
|
|
<p>This function always succeeds regardless of the drive status. No media access is occured in this function and it only initializes the given work area and registers its address to the internal table. The volume mount process is performed on first file access after f_mount function or media change.</p>
