"Deprecated" according to Microsoft. It's still part of the old (ancient) MS DOS terminal functions. That particular function lives on for its simple utility, and I assumed (incorrectly) that you were using the <conio.h> library. Sorry.
 That is, there is a commonly-known function with the same name... Most people won't think of NCurses's getch() first...[/edit]
NCurses is superior, so keep using it. (Good job!)
