I am trying to feed a stream of ASCII characters into the input.device. I'm trying to simulate keyboard activity. The input.device expects (optionally qualified) raw key presses and releases. So, to do what I want, for each character, I must determine a raw key code and appropriate qualifiers which will generate it. In other words, I need something like a RawKeyConvert() that runs backwards (accepts ASCII and produces a raw key event). The brute force way is to scan thru the entire KeyMap, trying to discover keycodes and qualifiers which generate each ASCII code, while filling up a lookup table. This turns out to be somewhat painful, since I don't completely understand the use of some KCF_DEAD key types and other such stuff. It's also messy enough that I feel there must be an easier way. What I really want, tho, is a more direct way to fake keyboard input. There are comments in "devices/inputevent.h" which suggest a IECLASS_ANSI may have once existed. Something like this would appear to be exactly what I need for tagging input events- like ie.ie_Code = <ascii code>; ie.ie_Class = IECLASS_ANSI (or IECLASS_ASCII even); How about: temporarily SetFunction()'ing RawKeyConvert() ?? Along with being kludgy and possibly dumb, this is probably impossible, since I think SetFunction() can only handle library, and not device, vectors. (?) How about: SetDefaultKeyMap()'ing my own simple KeyMap for the duration of the input injection period, and restoring afterwards ? This doesn't strike me as being too system-friendly. As you can tell, I'm groping for a solution here. Are there some tricks, hints, or tips that I have overlooked?? -scott

The function InvertKeyMap() in commodities.library (part of Commodities
Exchange) does what you want. Source has been distributed, but you
can't steal hunks of it wholesale. Perhaps you will find ikm.c
educational.
One good think about it living in a library (hopefully soon to be
semi-standard) is that it undoubtedly has bugs (none known) which can
be fixed retroactively for client programs by updating the library.
And don't forget dead keys.
