Member Typedef Documentation

◆ HostMap

typedef std::map<std::string, int> HostMap

A list of strings (used for server addresses) and ints (used for port numbers).

Member Function Documentation

◆ closeSocket()

void closeSocket ( int  fd,
const LogSink logInstance 
)
static

Closes the given socket.

Parameters
fdThe socket to close.
logInstanceA LogSink to use for logging.

Definition at line 518 of file dns.cpp.

◆ connect() [1/2]

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
hostThe host to resolve SRV records for.
logInstanceA LogSink to use for logging.
Returns
A file descriptor for the established connection.

Definition at line 247 of file dns.cpp.

◆ connect() [2/2]

int connect ( const std::string &  host,
int  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
hostThe host/IP address to connect to.
portA custom port to connect to.
logInstanceA LogSink to use for logging.
Returns
A file descriptor for the established connection.

Definition at line 412 of file dns.cpp.

◆ getSocket()

int getSocket ( const LogSink logInstance)
static

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

Parameters
logInstanceA LogSink to use for logging.
Returns
A TCP socket.

Definition at line 339 of file dns.cpp.

◆ resolve() [1/2]

static HostMap resolve ( const std::string &  domain,
const LogSink logInstance 
)
inlinestatic

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
domainThe domain to resolve SRV records for.
logInstanceA 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.

◆ resolve() [2/2]

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
serviceThe SRV service type.
protoThe SRV protocol.
domainThe domain to search for SRV records.
logInstanceA 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.
