}
  

Asynchronously overwrites the file in read-write mode, replacing the contents, possibly creating a backup copy of the file first.

For more details, see Gio.File.prototype.replace_readwrite which is the synchronous version of this call.

When the operation is finished, callback will be called. You can then call Gio.File.prototype.replace_readwrite_finish to get the result of the operation.
