| <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 only initializes the given work area and registers its address to the internal table, any access to the disk I/O layer does not occure. The volume mount process is performed on first file access after f_mount function or media change.</p> | |
