Momentics Console view

This works as expected in a terminal window:

int CharReady()
{
int n;

if ( ioctl(0, FIONREAD, &n) == -1 ) {
return -1;
} else {
return n;
}
}

int main()
{
while ( CharReady() != 2 ) {
printf(“type 2 characters to stop this printing…\n”);
sleep(1);
}

// code here to flush buffers
}

… but doesn’t “respond” to characters typed in a Console view. One hint:
in a terminal window, the characters typed are not echoed, but they are
echoed in a Console view. Would you happen to know how to get this to work
as desired in a Console view? Thanks.

The console view (under 6.2.1B and earlier) is not a terminal device.
It does not do character-by-character IO, but does line-oriented IO.
And, it may not even handle this ioctl.
What does CharReady() give after you hit enter on the console view?

It does not (currently) support this level of output. The best I can
suggest for doing what you seem to want – that is, to debug a program
that also does more than the simplest level of terminal I/O would be
to run the program in a telnet session (to get a real terminal), then
use the IDE’s “attach to running process” ability to bring that program
into the debugger.
