FileReadMoreCallback

When loading the partial contents of a file with g_file_load_partial_contents_async(), it may become necessary to determine if any more data from the file should be loaded. A #GFileReadMoreCallback function facilitates this by returning true if more data should be read, or false otherwise.

• param fileContents the data as currently read.

• param fileSize the size of the data currently read.

• return true if more data should be read back. false otherwise.
