#define CHECK_END_OF_RECORD do { \
if (ptr => end_of_record) { \
return NULL; \
} } while (0)
Then you can just put:
ptr += 2;
CHECK_END_OF_RECORD;
Or something like that.</pre>

In fact, the entire exercise here is mostly to figure out how long everything is so that things can be allocated.
This is a long routine; sometimes it's nice to take repetitive code and squish it down. If Mark feels like that injects too much risk, I have no problem with the finding being dropped.

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This adds NAPTR support for DNS in Asterisk.
The main parts of this are the functions for allocating a DNS NAPTR record when a resolver wishes to add a NAPTR record, the sorting algorithm for sorting DNS NAPTR records, and the tests that use a mock DNS resolver.
NOTE: There is likely to be some overlap here in this review and Josh's SRV review (/r/4528). Our stance on this is that we will factor out the duplicated code once both SRV and NAPTR have been merged into the main DNS branch. The factoring out of common functions will be placed in its own review.</pre>
