fat.UnInit

#include <file_config.h>

BOOL UnInit  (
     U32 mode);      /* Uninit mode; IO or Media */

The function UnInit de-initializes the FAT driver.

The parameter mode specifies the de-initialization mode:

The function is part of the FAT Driver. The prototype is defined in the file File_Config.h. Developers must customize the function.

The function is called twice by the function funinit. First, with the argument DM_MEDIA; next, with the argument DM_IO.

Use the function during run-time when the drive volume has to be disabled. For example, for reducing power consumption. Afterwards, call only the function finit for re-initializing the drive.

• __TRUE - on success.
• __FALSE - on failure.
