Function Documentation

◆ coap_encode_var_bytes()

COAP_STATIC_INLINE COAP_DEPRECATED int coap_encode_var_bytes	(	uint8_t *	buf,
		unsigned int	value
	)

Deprecated:: Use coap_encode_var_safe() instead. Provided for backward compatibility. As value has a maximum value of 0xffffffff, and buf is usually defined as an array, it is unsafe to continue to use this variant if buf[] is less than buf[4].

For example char buf[1],oops; .. coap_encode_var_bytes(buf, 0xfff); would cause oops to get overwritten. This error can only be found by code inspection. coap_encode_var_safe(buf, sizeof(buf), 0xfff); would catch this error at run-time and should be used instead.
