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.
RESULTS
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.
