Is there a standard getch() equivalent in C++?

Question

I know that getch is not a standard C/C++ function but I tend to like it because it doesn't need you to press enter before returning. So I'd like to know if there is any equivalent in standard C++ that has the same effect (doesn't require you to press enter)?

I have read similar questions on this site but none of their answers say whether there is a standard and portable equivalent or not.

If there were a function like that, you would've probably seen it used in some of the answers you say you read. — jrok, Jul 22 '13 at 11:25
I believe it's quite hard to have it in standard, since standard doesn't say when console will give data to your program. — RiaD, Jul 22 '13 at 11:26
Why not just use a combination of fopen(stdin) and fgetc() ? — bkausbk, Jul 22 '13 at 11:35
`fgetc(stdin)` does exactly the same thing as `getchar()`, which in most implementations is line-buffered (that is, waits for the user to hit "enter"). — Mats Petersson, Jul 22 '13 at 11:42

There is a portable-ish equivalent if you use one of the "curses" libraries, such as ncurses

Use ncurses. It's the best and simplest alternative out there.

Sample Code:

#include <ncurses.h>

 int main()
 {  
   initscr();                   /* Start curses mode          */
   printw("Hello World !!!");   /* Print Hello World          */
   refresh();                   /* Print it on to the real screen */
   getch();                     /* Wait for user input */
   endwin();                    /* End curses mode        */

   return 0;
 }

Is there a standard getch() equivalent in C++?
