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.
