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:
GResolverRecordTypeThe type of DNS record to look up.
cancellable-
Type:
GCancellableA
GCancellable, orNULL.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 aNULLGError*.The argument will be left initialized to NULLby 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.).
