Member Function Documentation

void closeSocket (  int  fd  )  [static]
 

Closes the given socket.

Parameters:
fd The socket to close.

Definition at line 314 of file dns.cpp.

int connect (  const std::string &  host,
unsigned short  port,
const LogSink &  logInstance
)  [static]
 

This is a convenience function which connects to the given host and port. No SRV records are resolved. Use this function for special setups.

Parameters:
host The host/IP address to connect to.
port A custom port to connect to.
logInstance A LogSink to use for logging.
Returns:
A file descriptor for the established connection.

Definition at line 262 of file dns.cpp.

int connect (  const std::string &  host,
const LogSink &  logInstance
)  [static]
 

This is a convenience function which uses resolve() to get a list of hosts and connects to one of them.

Parameters:
host The host to resolve SRV records for.
logInstance A LogSink to use for logging.
Returns:
A file descriptor for the established connection.

Definition at line 210 of file dns.cpp.

int getSocket (   )  [static]
 

A convenience function that prepares and returnes a simple, unconnected TCP socket.

Returns:
A TCP socket.

Definition at line 227 of file dns.cpp.

static HostMap resolve (  const std::string &  domain,
const LogSink &  logInstance
)  [inline, static]
 

This is a convenience funtion which uses resolve() to resolve SRV records for a given domain, using a service of xmpp-client and a proto of tcp.

Parameters:
domain The domain to resolve SRV records for.
logInstance A LogSink to use for logging.
Returns:
A list of weighted hostname/port pairs from SRV records, or A records if no SRV records where found.

Definition at line 90 of file dns.h.

DNS::HostMap resolve (  const std::string &  service,
const std::string &  proto,
const std::string &  domain,
const LogSink &  logInstance
)  [static]
 

This function resolves a service/protocol/domain tuple.

Parameters:
service The SRV service type.
proto The SRV protocol.
domain The domain to search for SRV records.
logInstance A LogSink to use for logging.
Returns:
A list of weighted hostname/port pairs from SRV records, or A records if no SRV records where found.
