Virtual Method

GioResolverlookup_records

since: 2.34

Declaration [src] 

GList*
lookup_records (
  GResolver* resolver,
  const gchar* rrname,
  GResolverRecordType record_type,
  GCancellable* cancellable,
  GError** error
)

Description [src]

Synchronously performs a DNS record lookup for the given rrname and returns a list of records as GVariant tuples. See GResolverRecordType for information on what the records contain for each record_type.

If the DNS resolution fails, error (if non-NULL) will be set to a value from GResolverError and NULL will be returned.

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.

Available since: 2.34

Parameters

rrname

Type: const gchar*

The DNS name to look up the record for.

The data is owned by the caller of the method.
The value is a NUL terminated UTF-8 string.
record_type

Type: GResolverRecordType

The type of DNS record to look up.

cancellable

Type: GCancellable

A GCancellable, or NULL.

The argument can be NULL.
The data is owned by the caller of the method.
error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.
If the return location is not NULL, then you must initialize it to a NULL GError*.
The argument will be left initialized to NULL by the virtual function if there are no errors.
In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: A list of GVariant*

A non-empty GList of GVariant, or NULL on error. You must free each of the records and the list when you are done with it. (You can use g_list_free_full() with g_variant_unref() to do this.).

The caller of the method takes ownership of the returned data, and is responsible for freeing it.
