Function Documentation

int coap_block1_handler	(	void *	request,
		void *	response,
		uint8_t *	target,
		size_t *	len,
		size_t	max_len
	)

Block 1 support within a coap-ressource.

   This function will help you to use block 1. If target is null
   error handling and response configuration is active. On return
   value 0, the last block was recived, while on return value 1
   more blocks will follow. With target, len and maxlen this
   function will assemble the blocks.

   You can find an example in:
   examples/er-rest-example/resources/res-b1-sep-b2.c

Parameters

request	Request pointer from the handler
response	Response pointer from the handler
target	Pointer to the buffer where the request payload can be assembled
len	Pointer to the variable, where the function stores the actual length
max_len	Length of the "target"-Buffer

Returns

0 if initialisation was successful -1 if initialisation failed
