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.
