gResolverLookupByAddress {RGtk2} | R Documentation

## gResolverLookupByAddress

### Description

Synchronously reverse-resolves `address` to determine its associated hostname.

### Usage

    gResolverLookupByAddress(object, address, cancellable = NULL,
        .errwarn = TRUE)

### Arguments

``object`` | a `GResolver`
``address`` | the address to reverse-resolve
``cancellable`` | a `GCancellable`, or `NULL`
`.errwarn` | Whether to issue a warning on error or fail silently

### Details

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`. Since 2.22

### Value

A list containing the following elements:

`retval` | [character] a hostname (either ASCII-only, or in ASCII-encoded form), or `NULL` on error.
``error`` | return location for a `GError`, or `NULL`
