|
|
* \brief
|
|
* The DNS clientinfo interface allows libdns to retrieve information
|
|
* about the client from the caller.
|
|
*
|
|
* The clientinfo interface is used by the DNS DB and DLZ interfaces;
|
|
* it allows databases to modify their answers on the basis of information
|
|
* about the client, such as source IP address.
|
|
*
|
|
* dns_clientinfo_t contains a pointer to an opaque structure containing
|
|
* client information in some form. dns_clientinfomethods_t contains a
|
|
* list of methods which operate on that opaque structure to return
|
|
* potentially useful data. Both structures also contain versioning
|
|
* information.
