The most Xcode-ish way to do this is to add /usr/lib/libcurses.dylib to
your project.
Finally, if anyone would care to tell me why my code is acting funny,
I'd appreciate it! :)
(it's acting as though it only sees a character after the subsequent
character is pressed.)
do
{
foo = getch();
printf("Character was: %c\n",foo);
}while (foo!='q');
That's because printf writes to stdout, which is buffered by default.
stderr is not buffered, so you can either use
fprintf(stderr, "Character was: %c\n", foo);
or
printf("Character was: %c\n", foo);
fflush(stdout);
(Tip: You could figure this out by running the program, attaching to it
with gdb from another window, and putting a breakpoint on the printf
line. Then you'd see that when you hit that line foo has the expected
value, but the output doesn't actually appear on your screen until the
next time around.)
Hope this helps,
Eric
