Hex.Document.write_to_file_async

### Method

# Hex Documentwrite_to_file_async

#### Declaration

    void
    hex_document_write_to_file_async (
      HexDocument* doc,
      GFile* file,
      GCancellable* cancellable,
      GAsyncReadyCallback callback,
      gpointer user_data
    )

#### Description

Write the buffer to `file` asynchronously. This can be used for a ‘Save As’ operation. This is the non-blocking version of `hex_document_write_to_file()`.

Note that for both this method and `hex_document_write_async()`, `hex_document_write_finish()` is the method to retrieve the return value in your `GAsyncReadyCallback` function.

This method completes asynchronously. Use `hex_document_write_finish()` inside the `GAsyncReadyCallback` to obtain the result of the operation.
