Import r67258 of the wxWidgets trunk, which I expect will before
long become wxWidgets 2.9.2, which in turn is expected to be the last 2.9 release before the 3.0 stable release. Since the full wxWidgets distribution is rather large, I have imported only the parts that we use, on a subdirectory basis: art include/wx/*.* include/wx/aui include/wx/cocoa include/wx/generic include/wx/gtk include/wx/meta include/wx/msw include/wx/osx include/wx/persist include/wx/private include/wx/protocol include/wx/unix src/aui src/common src/generic src/gtk src/msw src/osx src/unix git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@7380 8ced0084-cf51-0410-be5f-012b33b47a6e

/*
|

* Mini-DDE implementation
|
||||
|
||||
Most transactions involve a topic name and an item name (choose these
|
||||
as befits your application).
|
||||
|
||||
A client can:
|
||||
|
||||
- ask the server to execute commands (data) associated with a topic
|
||||
- request data from server by topic and item
|
||||
- poke data into the server
|
||||
- ask the server to start an advice loop on topic/item
|
||||
- ask the server to stop an advice loop
|
||||
|
||||
A server can:
|
||||
|
||||
- respond to execute, request, poke and advice start/stop
|
||||
- send advise data to client
|
||||
|
||||
Note that this limits the server in the ways it can send data to the
|
||||
client, i.e. it can't send unsolicited information.
