|An asynchronous DNS resolver based on GNU ADNS
http://www.gnu.org/software/adns/. You should link your
program with the threaded runtime-system when using this
module. In GHC, this is accomplished by specifying -threaded
on the command-line.
|A Resolver is an IO computation which -- given the name
and type of the record to query -- returns an MVar that will
eventually contain the Answer from the Domain Name System.
|Run the given IO computation with an Initialized
Resolver. Note that resolver functions can be shared,
and should be shared between any number of IO
threads. You may use multiple resolvers, of course, but
doing so defeats the purpose of an asynchronous resolver.
|NoEnv||do not look at environment
|NoErrPrint||never print output to stderr (Debug overrides)
|NoServerWarn||do not warn to stderr about duff nameservers etc
|Debug||enable all output to stderr plus Debug msgs
|LogPid||include process id in diagnostic output
|NoAutoSys||do not make syscalls at every opportunity
|Eintr||allow adnsSynch to return eINTR
|NoSigPipe||application has SIGPIPE set to SIG_IGN, do not protect
|CheckC_EntEx||do consistency checks on entry/exit to adns functions
|CheckC_Freq||do consistency checks very frequently (slow!)
|Use this function to disable DNS resolving. It will
always return (Answer sSYSTEMFAIL Nothing (Just
host) (-1) ).
