LFS_read_file_checksum_sha256()

int8_t LFS_read_file_checksum_sha256	(	const char	filepath[],
		uint32_t	start_offset,
		uint32_t	max_length,
		uint8_t	sha256_dest[32] )

Computes the SHA256 checksum of a file in LittleFS.

Parameters

filepath	Path to the file to read and compute the checksum for.
start_offset	The offset in the file from which to start reading.
max_length	The maximum number of bytes to read from the file. 0 means read the entire file.
sha256_dest	32-byte array to be filled with checksum.

Returns

0 on success. Negative LFS error codes on error.
