libasyncns is a C library for Linux/Unix for executing name service queries
|
|
asynchronously. It is an asynchronous wrapper around getaddrinfo(3),
|
|
getnameinfo(3), res_query(3) and res_search(3) from libc and libresolv.
|
|
|
|
In contrast to GNU's asynchronous name resolving API getaddrinfo_a(),
|
|
libasyncns does not make use of UNIX signals for reporting completion of name
|
|
queries. Instead, the API exports a standard UNIX file descriptor which may be
|
|
integerated cleanly into custom main loops.
|
|
|
|
In contrast to asynchronous DNS resolving libraries like libdenise, skadns,
|
|
adns, libasyncns is just an asynchronous wrapper around the libc's synchronous
|
|
getaddrinfo() API, which has the advantage of allowing name resolution using
|
|
techniques like Multicast DNS, LDAP or NIS using standard libc NSS (Name
|
|
Service Switch) modules. libasyncns is compatible with IPv6 if the underlying
|
|
libc is.
|
|
|
|
libasyncns is very tiny, consisting of just one header and one source file. It
|
|
has no dependencies besides libc.
