Information for Phoenix Developers on using libcoap

Adding data to a coap message

libcoap provides a call coap_add_data() which behaves similar as memcpy, i.e., you specify the number of bytes that you want to add.

Attention: In case you want to add a string to a coap message and you use strlen() to determine the number of bytes in the string, keep in mind that strlen() dos not account for the terminating null-character. So, if you want to add the terminating null-character as well via coap_add_data(), you have to pass strlen() + 1 to coap_add_data().
