Parameters

w  (wnd) The window.

dataId  (int) Data id. It is COPYDATASTRUCT.dwData.

send  (ReadOnlySpan<TSend>) Data to send. For example string or byte[]. String can contain '\0' characters.

receive  (WndCopyData.ResultReader<TReceive>) Callback function that can convert the received data to desired format.
