[FAT16 support]

Detailed Description

Basic functions for handling a FAT16 filesystem.

Functions
struct fat16_fs_struct *	fat16_open (struct partition_struct *partition)
	Opens a FAT16 filesystem.
void	fat16_close (struct fat16_fs_struct *fs)
	Closes a FAT16 filesystem.
uint32_t	fat16_get_fs_size (const struct fat16_fs_struct *fs)
	Returns the amount of total storage capacity of the filesystem in bytes.
uint32_t	fat16_get_fs_free (const struct fat16_fs_struct *fs)
	Returns the amount of free storage capacity on the filesystem in bytes.

Function Documentation

struct fat16_fs_struct* fat16_open

(

struct partition_struct *

partition

)

[read]

Opens a FAT16 filesystem.

Parameters:

[in]

partition

Discriptor of partition on which the filesystem resides.

Returns:

0 on error, a FAT16 filesystem descriptor on success.

See also:

fat16_open

void fat16_close

(

struct fat16_fs_struct *

fs

)

Closes a FAT16 filesystem.

When this function returns, the given filesystem descriptor will be invalid.

Parameters:

[in]

fs

The filesystem to close.

See also:

fat16_open

uint32_t fat16_get_fs_size

(

const struct fat16_fs_struct *

fs

)

Returns the amount of total storage capacity of the filesystem in bytes.

Parameters:

[in]

fs

The filesystem on which to operate.

Returns:

0 on failure, the filesystem size in bytes otherwise.

uint32_t fat16_get_fs_free

(

const struct fat16_fs_struct *

fs

)

Returns the amount of free storage capacity on the filesystem in bytes.

Note:

As the FAT16 filesystem is cluster based, this function does not return continuous values but multiples of the cluster size.

Parameters:

[in]

fs

The filesystem on which to operate.

Returns:

0 on failure, the free filesystem space in bytes otherwise.
