%description |

|
|
|
adns is a resolver library for C (and C++) programs. In contrast with the |
|
|
|
|
existing interfaces, gethostbyname et al. and libresolv, it has the |
|
|
|
|
following features: |
|
|
|
|
* It is reasonably easy to use for simple programs which just want to |
|
|
|
|
translate names to addresses, look up MX records, etc. |
|
|
|
|
* It can be used in an asynchronous, nonblocking, manner. Many queries |
|
|
|
|
can be handled simultaneously. |
|
|
|
|
* Responses are decoded automatically into a natural representation for |
|
|
|
|
a C program - there is no need to deal with DNS packet formats. |
|
|
|
|
* Sanity checking (e.g., name syntax checking, reverse/forward |
|
|
|
|
correspondence, CNAME pointing to CNAME) is performed automatically. |
|
|
|
|
* Time-to-live, CNAME and other similar information is returned in an |
|
|
|
|
easy to use form, without getting in the way. |
|
|
|
|
* There is no global state in the library; resolver state is an opaque |
|
|
|
|
data structure which the client creates explicitly. A program can have |
|
|
|
|
several instances of the resolver. |
|
|
|
|
* Errors are reported to the application in a way that distinguishes the |
|
|
|
|
various causes of failure properly. |
|
|
|
|
* Understands conventional resolv.conf, but this can overridden by |
|
|
|
|
environment variables. |
|
|
|
|
* Flexibility. For example, the application can tell adns to: ignore |
|
|
|
|
environment variables (for setuid programs), disable sanity checks e.g. |
|
|
|
|
to return arbitrary data, override or ignore resolv.conf in favour of |
|
|
|
|
supplied configuration, etc. |
|
|
|
|
* Believed to be correct! For example, will correctly back off to TCP |
|
|
|
|
in case of long replies or queries, or to other nameservers if several |
|
|
|
|
are available. It has sensible handling of bad responses etc. |
