hostname to determine its associated IP
address(es). hostname may be an ASCII-only or UTF-8 hostname, or
the textual form of an IP address (in which case this just becomes
a wrapper around gInetAddressNewFromString).gResolverLookupByName(object, hostname, cancellable = NULL, .errwarn = TRUE)objecthostnamecancellableGCancellable, or NULLlist of GInetAddress, or NULL on error. You
must unref each of the addresses and free the list when you are
done with it. (You can use gResolverFreeAddresses to do this.)errorGError, or NULLgResolverLookupByName will return a list of
GInetAddress, sorted in order of preference. (That is, you should
attempt to connect to the first address first, then the second if
the first fails, etc.)
If the DNS resolution fails, error (if non-NULL) will be set to a
value from GResolverError.
If cancellable is non-NULL, it can be used to cancel the
operation, in which case error (if non-NULL) will be set to
G_IO_ERROR_CANCELLED.
If you are planning to connect to a socket on the resolved IP
address, it may be easier to create a GNetworkAddress and use its
GSocketConnectable interface.
