Method

GioFileload_partial_contents_async

Declaration 

void
g_file_load_partial_contents_async (
  GFile* file,
  GCancellable* cancellable,
  GFileReadMoreCallback read_more_callback,
  GAsyncReadyCallback callback,
  gpointer user_data
)

Description

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.

This method is not directly available to language bindings.
