Member Function Documentation

bool File_flash_avr32::close

(

)

[virtual]

Close the file.

Returns:

success

Implements File.

int8_t File_flash_avr32::exists

(

const char *

path

)

[virtual]

Indicates if the file exits.

Returns:

1 if the file exists, 0 if the file doesn't exist, -1 if the file system is not responding properly

Implements File.

bool File_flash_avr32::flush

(

)

[virtual]

flush buffer to file

Returns:

success (always true)

Implements File.

bool File_flash_avr32::is_open

(

)

[virtual]

Indicates if the file is currently open.

Returns:

true if the file is open, false otherwise

Implements File.

uint32_t File_flash_avr32::length

(

)

[virtual]

Get the file length.

Returns:

The file length up to the maximum supported 4Gb.

Implements File.

uint32_t File_flash_avr32::offset

(

)

[virtual]

Get current location in file.

Returns:

Offset in bytes

Implements File.

Here is the caller graph for this function:

bool File_flash_avr32::open

(

const char *

path

)

[virtual]

Open the file.

Returns:

true if the file is open, false otherwise

Implements File.

bool File_flash_avr32::read	(	uint8_t *	data,
		uint32_t	size
	)		[virtual]

Read from the file.

Parameters:

data	Caller supplied buffer to write to.
size	The number of bytes to attempt to read.

Returns:

success

Implements File.

bool File_flash_avr32::seek	(	int32_t	offset,
		file_seekfrom_t	origin
	)		[virtual]

Seek to a given offset within the file.

Valid locations to seek to are from zero to the file length. Seeking to the file length moves the pointer to one past the end of the file data so that subsequent file writes append to the existing file.

Parameters:

offset	The distance to move from the origin_ parameter.
origin	One of the SeekFrom enumeration.

Returns:

success

Implements File.

Here is the call graph for this function:

bool File_flash_avr32::write	(	const uint8_t *	data,
		uint32_t	size
	)		[virtual]

Write to the file.

Parameters:

data	The buffer to write.
size	The number of bytes to write.

Returns:

success

Implements File.
