Part: Example of Receiving Messages

Sample code is:

ETERM *arr[2], *answer;
int sockfd,rc;
char buf[BUFSIZE];
ErlMessage emsg;

if ((rc = erl_receive_msg(sockfd , buf, BUFSIZE, &emsg)) == ERL_MSG) {
   arr[0] = erl_mk_atom("goodbye");
   arr[1] = erl_element(1, emsg.msg);
   answer = erl_mk_tuple(arr, 2);
   erl_send(sockfd, arr[1], answer);*   erl_free_term(answer);*

why erl_free_term() instead of erl_free_compound ?
>From my own tests erl_free_term() is not enough...

I then think that this code leaks memory.

Maybe I'm completely wrong ?
