Method
GioFileInputStreamquery_info_async
Declaration [src]
void
g_file_input_stream_query_info_async (
GFileInputStream* stream,
const char* attributes,
int io_priority,
GCancellable* cancellable,
GAsyncReadyCallback callback,
gpointer user_data
)
Description [src]
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.
This method completes asynchronously. Use g_file_input_stream_query_info_finish() inside the GAsyncReadyCallback to obtain the result of the operation.
