Function Documentation

golioth_payload_as_bool()

bool golioth_payload_as_bool	(	const uint8_t *	payload,
		size_t	payload_size )

Convert raw byte payload into a bool

Parameters

payload	Pointer to payload data
payload_size	Size of payload, in bytes

Return values

true	payload is exactly the string "true"
false	otherwise

golioth_payload_as_float()

float golioth_payload_as_float	(	const uint8_t *	payload,
		size_t	payload_size )

Convert raw byte payload into a float

Parameters

payload	Pointer to payload data
payload_size	Size of payload, in bytes

Returns

float value returned from strtof(payload, NULL)

golioth_payload_as_int()

int32_t golioth_payload_as_int	(	const uint8_t *	payload,
		size_t	payload_size )

Convert raw byte payload into an int32_t

Parameters

payload	Pointer to payload data
payload_size	Size of payload, in bytes

Returns

int32_t value returned from strtol(payload, NULL, 10)

golioth_payload_is_null()

bool golioth_payload_is_null	(	const uint8_t *	payload,
		size_t	payload_size )

Returns true if payload has no contents

Parameters

payload	Pointer to payload data
payload_size	Size of payload, in bytes

Return values

true	payload is NULL, payload_size is 0 or payload is exactly the string "null"
false	otherwise
