The bug report contains a code snippet that itself contains a bug. The second code snippet: len = sizeof(buf); read_config_read_octet_string(str, (u_char**)&buf, &len); snmp_log(LOG_INFO, "len:%d, buf:%s\n", len, buf);
The second param to read_config_read_octet_string should be a pointer to a pointer to the buffer. In this case it is just passing in a pointer to the buffer. In other words, not enough redirection. Try: pt = buf; /* or to better illustrate, pt = &buf[0] */ len = sizeof(buf); read_config_read_octet_string(str, &pt, &len); snmp_log(LOG_INFO, "len:%d, buf:%s\n", len, buf); There are also multiple examples of correct usage in snmplib/vacm.c -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Tuesday, September 28, 2004 4:48 AM To: [EMAIL PROTECTED] Subject: Re: Am I confused or is read_config_read_octet_string broken? > ... > I'd say that the basic problem here is that the behaviour is not > documented properly.

As noted in bug 1029287, this "correct approach" seems to have a bug in its implementation. http://sourceforge.net/tracker/index.php?func=detail&aid=1029287&group_i d=12694&atid=112694 ------------------------------------------------------- This SF.Net email is sponsored by: YOU BE THE JUDGE.
