Desc: A reverse lookup on an IP address leads to a lookup per returned PTR answer to see if the returned answer matches. The forward lookups are handled by a separate function which calls gethostbyname. Upon a single successful match of a forward lookup with a reverse lookup, returns SPF_TRUE. Returns SPF_FALSE upon failure. Definition at line <a class="el" href="dns_8c-source.html#l00716">716</a> of file <a class="el" href="dns_8c-source.html">dns.c</a>. |
