Data Structures
struct	coap_block_t
	Structure of Block options. More...

Macros
#define	COAP_MAX_BLOCK_SZX   6
	The largest value for the SZX component in a Block option. More...
#define	COAP_OPT_BLOCK_LAST(opt)   (coap_opt_length(opt) ? (coap_opt_value(opt) + (coap_opt_length(opt)-1)) : 0)
	Returns the value of the least significant byte of a Block option opt. More...
#define	COAP_OPT_BLOCK_MORE(opt)   (coap_opt_length(opt) ? (*COAP_OPT_BLOCK_LAST(opt) & 0x08) : 0)
	Returns the value of the More-bit of a Block option opt. More...
#define	COAP_OPT_BLOCK_SZX(opt)   (coap_opt_length(opt) ? (*COAP_OPT_BLOCK_LAST(opt) & 0x07) : 0)
	Returns the value of the SZX-field of a Block option opt. More...

Functions
unsigned int	coap_opt_block_num (const coap_opt_t *block_opt)
	Returns the value of field num in the given block option block_opt. More...
COAP_STATIC_INLINE int	coap_more_blocks (size_t data_len, unsigned int num, uint16_t szx)
	Checks if more than num blocks are required to deliver data_len bytes of data for a block size of 1 << (szx + 4). More...
int	coap_get_block (coap_pdu_t *pdu, uint16_t type, coap_block_t *block)
	Initializes block from pdu. More...
int	coap_write_block_opt (coap_block_t *block, uint16_t type, coap_pdu_t *pdu, size_t data_length)
	Writes a block option of type type to message pdu. More...
int	coap_add_block (coap_pdu_t *pdu, unsigned int len, const uint8_t *data, unsigned int block_num, unsigned char block_szx)
	Adds the block_num block of size 1 << (block_szx + 4) from source data to pdu. More...
void	coap_add_data_blocked_response (struct coap_resource_t *resource, struct coap_session_t *session, coap_pdu_t *request, coap_pdu_t *response, const coap_binary_t *token, uint16_t media_type, int maxage, size_t length, const uint8_t *data)
	Adds the appropriate part of data to the response pdu. More...
