ZB_ZCL_FINISH_PACKET

#define ZB_ZCL_FINISH_PACKET	(		zbbuf,
			ptr
	)		(void) zb_zcl_finish_and_send_packet((zbbuf), (ptr),

Finish ZCL packet filling. Used bytes number are marked in a buffer.

Parameters

zbbuf	- pointer to zb_buf_t buffer.
ptr	- pointer to the byte after the last written byte in the buffer.

Attention

After ZB_ZCL_FINISH_PACKET() call, pointer ptr is set to the beginning of the buffer data.

Note

Please note that this macro does not return ret code, so if this macro is used without callback, this may lead to buffer leaks (if function is failed to send the packet). Please use zb_zcl_finish_and_send_packet() function directly to be able to check ret code.
