File.loadPartialContentsAsync

Reads the partial contents of a file. A GFileReadMoreCallback should be used to stop reading from the file when appropriate, else this function will behave exactly as g_file_load_contents_async(). This operation can be finished by g_file_load_partial_contents_finish(). Users of this function should be aware that user_data is passed to both the read_more_callback and the callback. 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.

a GFileReadMoreCallback to receive partial data and to specify whether further data should be read

callback GAsyncReadyCallback

a GAsyncReadyCallback to call when the request is satisfied

userData void*
