Description¶
IP contains some support functions for the IPv4 protocol. TCP/IP support is in different classes (see StreamPeerTCP and TCP_Server). IP provides hostname resolution support, both blocking and threaded.
Member Function Description¶
- void clear_cache ( String arg0=”” )
- void erase_resolve_item ( int id )
Erase a queue ID, removing it from the queue if needed. This should be used after a queue is completed to free it and enable more queries to happen.
- Array get_local_addresses ( ) const
Return a resolved item address, or an empty string if an error happened or resolution didn’t happen yet (see get_resolve_item_status).
Return the status of hostname queued for resolving, given its queue ID. Returned status can be any of the RESOLVER_STATUS_* enumeration.
Resolve a given hostname, blocking. Resolved hostname is returned as an IPv4 or IPv6 depending on “ip_type”.
Create a queue item for resolving a given hostname to an IPv4 or IPv6 depending on “ip_type”. The queue ID is returned, or RESOLVER_INVALID_ID on error.
