Member Function Documentation

void DNSManager::AddCache ( DNSQuery & r )

Add a record to the dns cache

Parameters:

r

The record

DNSQuery DNSManager::BlockingQuery	(	const Anope::string &	mask,
		QueryType	qt
	)			`[static]`

Does a BLOCKING DNS query and returns the first IP. Only use this if you know what you are doing. Unless you specifically need a blocking query use the DNSRequest system

bool DNSManager::CheckCache ( DNSRequest * request )

Check the DNS cache to see if request can be handled by a cached result
