gSocketAddressEnumeratorNext {RGtk2} | R Documentation

## 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`.
