pollMountable
Polls a file of type %G_FILE_TYPE_MOUNTABLE.
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 returned.
When the operation is finished, @callback will be called. You can then call g_file_mount_mountable_finish() to get the result of the operation.
