This function sets a callback that is invoked after the socket is
created, but before the connection is established. This is an ideal
time to customize various socket options.
Add user-visible entrypoints ares_{get,set}_servers_ports(3), which
take struct ares_addr_port_node rather than struct ares_addr_node.
This structure includes a UDP and TCP port number; if this is set
to zero, the channel-wide port values are used as before.
Similarly, add a new ares_set_servers_ports_csv(3) entrypoint, which
is analogous to ares_set_servers(3) except it doesn't ignore any
specified port information; instead, any per-server specified port
is used as both the UDP and TCP port for that server.
The internal struct ares_addr is extended to hold the UDP/TCP ports,
stored in network order, with the convention that a value of zero
indicates that the channel-wide UDP/TCP port should be used.
For the internal implementation of ares_dup(3), shift to use the
_ports() version of the get/set functions, so port information is
transferred correctly to the new channel.
Update manpages, and add missing ares_set_servers_csv to the lists
while we're at it
Allow explicit configuration of the channel's sortlist, by
specifying a string in the same format as the equivalent
/etc/resolv.conf option.
This allows library users to perform the same configuration
that is available via /etc/resolv.conf, but without needing
to change that file.
Make sure that the symbols are always exported and present in c-ares.
Make the headers prefixed with 'ares'.
Removed the inet_ntop.h version as it no longer features any content.
I need to do SOA queries, so here is a parser for them.
- ares_soa_reply: new struct
- ares_malloc_data/ares_free_soa: ARES_DATATYPE_SOA_REPLY
- ares_parse_soa_reply: actual function
ares_parse_txt_reply() current version:
- Fixed a couple of potential double free's.
- Fixed memory leaks upon out of memory condition.
- Fixed pointer arithmetic.
- Setting ntxtreply to zero upon entry for all failure cases.
- Changed data type to size_t for variables substr_len, str_len and
the length member of ares_txt_reply struct.
- Avoided a couple of memcpy() calls.
- Changed i data type to unsigned int to prevent compiler warnings.
- Adjusted a comment.
- Use ARES_SUCCESS literal for successfull completion.
- Added CVS Id tag.
