Function Documentation

u32 nandfs_get_usage

(

void

)

Gets what percentage of the NAND FS is used.

Returns:

The percentage of used blocks.

s32 nandfs_initialize

(

void

)

Initializes the NAND FS.

Returns:

0 on success, anything else is failure.

s32 nandfs_open	(	struct nandfs_fp *	fp,
		const char *	path
	)

Opens a NAND FS file for reading.

Parameters:

	fp	the file pointer to store the file information.
	path	the path to the file to open.

Returns:

0 on success, anything else is failure.

s32 nandfs_read	(	void *	ptr,
		u32	size,
		u32	nmemb,
		struct nandfs_fp *	fp
	)

Reads data from a file on the NAND FS.

Parameters:

	ptr	the memory to read into.
	size	the size of each element to read.
	nmemb	how many elements to read.
	fp	the file pointer to read data from.

Returns:

How many bytes have been read.

s32 nandfs_seek	(	struct nandfs_fp *	fp,
		s32	offset,
		u32	whence
	)

Seeks to a position in a file.

Parameters:

	fp	the file pointer to seek in.
	offset	the offset to seek.
	whence	where to seek from.

Returns:

0 on success, anything else is failure.
