29 * When the plug and socket are in separate processes they use a
30 * simple protocol, more or less based on XEMBED. The protocol uses
31 * registered window messages. The name passed to
32 * RegisterWindowMessage() is gtk-win32-embed:%d, with %d being the
33 * numeric value of an GtkWin32EmbedMessageType enum. Each message
34 * carries the message type enum value and two integers, the "wparam"
35 * and "lparam", like all window messages.
37 * So far all the window messages are posted to the other
38 * process. Maybe some later enhancement will add also messages that
39 * are sent, i.e. where the sending process waits for the receiving
40 * process's window procedure to handle the message.
