coap_decode_var_bytes()

unsigned int coap_decode_var_bytes	(	const uint8_t *	buf,
		unsigned int	length
	)

Decodes multiple-length byte sequences.

buf points to an input byte sequence of length length. Returns the decoded value.

Parameters

buf	The input byte sequence to decode from
length	The length of the input byte sequence

Returns

The decoded value

coap_encode_var_safe()

unsigned int coap_encode_var_safe	(	uint8_t *	buf,
		size_t	length,
		unsigned int	value
	)

Encodes multiple-length byte sequences.

buf points to an output buffer of sufficient length to store the encoded bytes. value is the value to encode. Returns the number of bytes used to encode value or 0 on error.

Parameters

buf	The output buffer to decode into
length	The output buffer size to encode into (must be sufficient)
value	The value to encode into the buffer

Returns

The number of bytes used to encode value or 0 on error.
