gSocketAddressEnumeratorNext

Description

Retrieves the next GSocketAddress from enumerator. Note that this may block for some amount of time. (Eg, a GNetworkAddress may need to do a DNS lookup before it can return an address.) Use gSocketAddressEnumeratorNextAsync if you need to avoid blocking.

Usage

gSocketAddressEnumeratorNext(object, cancellable = NULL, .errwarn = TRUE)

Arguments

`object`	a `GSocketAddressEnumerator`
`cancellable`	optional `GCancellable` object, `NULL` to ignore.
`.errwarn`	Whether to issue a warning on error or fail silently

Details

If enumerator is expected to yield addresses, but for some reason is unable to (eg, because of a DNS error), then the first call to gSocketAddressEnumeratorNext will return an appropriate error in *error. However, if the first call to gSocketAddressEnumeratorNext succeeds, then any further internal errors (other than cancellable being triggered) will be ignored.

Value

A list containing the following elements:

`retval`	[`GSocketAddress`] or `NULL` on error (in which case *`error` will be set) or if there are no more addresses.
`error`	a `GError`.
