| domain | The domain to resolve SRV records for. |
| logInstance | A LogSink to use for logging. |
- Returns
- A file descriptor for the established connection.

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

This funtion 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.

inlinestatic |
This is a convenience funtion which uses resolve() to resolve SRV records for a given domain, using a service of xmpp 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.
