NAME

	RawKeyConvert -- decode raw input classes

SYNOPSIS

	actual = RawKeyConvert(event, buffer, length, keyMap)
	D0       	       A0     A1      D1      A2
	ConsoleDevice in A6 if called from Assembly Language.

FUNCTION

	This console function converts input events of type
	IECLASS_RAWKEY to ANSI bytes, based on the keyMap, and
	places the result into the buffer.

INPUTS

	event -  an InputEvent structure pointer.
	buffer - a byte buffer large enough to hold all anticipated
	    characters generated by this conversion.
	length - maximum anticipation, i.e. the buffer size in bytes.
	keyMap - a KeyMap structure pointer, or null if the default
	    console device key map is to be used.

RESULT

	actual - the number of characters in the buffer, or -1 if
	    a buffer overflow was about to occur.
    ERRORS
	if actual is -1, a buffer overflow condition was detected.
	Not all of the characters in the buffer are valid.

NOTES

	This function is different from standard device commands in
	that it is a function in the console device library vectors.
	In order to obtain a valid library base pointer for the
	console device (a.k.a. ConsoleDevice) call
	OpenDevice("console.device", -1, IOStdReq, 0),
	and then grab the io_Device pointer field out of the IOStdReq
	and use as ConsoleDevice.
