queryInfoAsync
open fun queryInfoAsync(attributes: String, ioPriority: Int, cancellable: Cancellable? = null, callback: AsyncReadyCallback)
Queries the stream information asynchronously. When the operation is finished @callback will be called. You can then call g_file_input_stream_query_info_finish() to get the result of the operation.
For the synchronous version of this function, see g_file_input_stream_query_info().
If @cancellable is not null, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error %G_IO_ERROR_CANCELLED will be set
Parameters
attributes
a file attribute query string.
ioPriority
the io-priority of the request
cancellable
optional #GCancellable object, null to ignore.
callback
callback to call when the request is satisfied
