Function Documentation

int logger_exfat_file_next ( const struct device * dev )

Stop logging to the current file, create the next file.

This function is intended for use when logging at extremely high frequencies, when the file creation overhead is problematic.

Warning: This function does not operate from the same context as normal logging, so care must be taken that logging is not occurring at the same time to avoid corruption of the current block counter.

Parameters

dev	exFAT logging device to move to the next file

Return values

0	on success
-errno	on failure

const char * logger_exfat_filesystem_claim	(	const struct device *	dev,
		uint8_t **	buf,
		size_t *	buf_size,
		k_timeout_t	timeout )

Claim exFAT filesystem.

Parameters

dev	exFAT logging device to claim filesystem for
buf	Block buffer that can be used for reads (Can be NULL if not needed)
buf_size	Size of the block buffer (Must be non-NULL if buf provided)
timeout	Duration to wait for filesystem object

Return values

disk	name on success
NULL	on timeout

void logger_exfat_filesystem_release ( const struct device * dev )

Release filesystem object claimed with logger_exfat_filesystem_claim.

Parameters

dev	exFAT logging device to release
