How deep is the Win32 message queue?

Question

How many messages does the queue for a standard window hold? What happens when the queue overflows? The documentation for GetMessage and relatives doesn't say anything about this, and PeekMessage only gives you a yes/no for certain classes of messages, not a message count. This page says that the queues are implemented using memory-mapped files, and that there is no message count limit, but that page is about WinCE. Does this apply to desktop Win32 as well?

Answer 1

10000 by default, but it can be adjusted via the registry. If queue overflows, PostMessage fails. Documentation here: PostMessage function on MSDN
