NAME
libfiredns - library for asynchronous DNS requests
SYNOPSIS
#include <firedns.h>
-lfiredns
DESCRIPTION
libfiredns is a library for handling asynchronous DNS requests. It
provides a very simple interface for sending requests and parsing
reponses, as well as low-timeout blocking functions. It can also be
compiled to override the BIND/LIBC functions with its alternative
implementations. libfiredns functions have much lower timeouts than
the stock functions and tend to be faster because they send requests to
all configured system nameservers at the same time.
Any function ending in "_r" is reentrant; it is safe to be used from
threaded programs, and it returns a dynamically allocated buffer which
must be free()'d later.
Any function ending in "_s" takes a buffer as a parameter that it will
write to.
Non-network functions:
firedns_aton4(3)
firedns_aton6(3)
firedns_ntoa4(3)
firedns_ntoa6(3)
Non-blocking functions:
firedns_getip4(3)
firedns_getip4list(3)
firedns_getip6(3)
firedns_getip6list(3)
firedns_gettxt(3)
firedns_gettxtlist(3)
firedns_getmx(3)
firedns_getmxlist(3)
firedns_getname4(3)
firedns_getname6(3)
firedns_getcname(3)
firedns_getresult(3)
Blocking functions:
firedns_resolveip4(3)
firedns_resolveip4list(3)
firedns_resolveip6(3)
firedns_resolveip6list(3)
firedns_resolvetxt(3)
firedns_resolvetxtlist(3)
firedns_resolvemx(3)
firedns_resolvemxlist(3)
firedns_resolvemxalist(3)
firedns_resolvename4(3)
firedns_resolvename6(3)
firedns_resolvecname(3)
Miscellaneous functions:

BUGS
This used to say:
FireDNS is very network unfriendly. It sends queries to all name‐
servers in /usr/local/etc/firedns.conf or (fallback) /etc/resolv.conf
at the same time. This loads the nameservers and the network much more
than existing implementations but tends to get responses much faster.
However, it seems that the network usage is well worth the 10 - 15%
speed increase (in ideal situations) that this program can provide. If
a primary nameserver is down, this speed increase is > 10000%.
