whats the difference between _kbhit and kbhit in C?

Question

I know kbhit "Determines if a keyboard key was pressed" but I see that people use both _kbhit and kbhit interchangeably.

`conio.h` is pretty obsolete. You should switch to something like `ncurses` — Eugene Sh., Jun 11 '21 at 19:41

`conio.h` is very obsolete and the functions are 100% non-portable to anything but windows. The curses library should be used if any type of portability is needed. — David C. Rankin, Jun 11 '21 at 20:27

According to this page on MSDN - kbhit is deprecated

The Microsoft-specific function name kbhit is a deprecated alias for the _kbhit function. By default, it generates Compiler warning (level 3) C4996. The name is deprecated because it doesn't follow the Standard C rules for implementation-specific names. However, the function is still supported.

We recommend you use _kbhit instead. Or, you can continue to use this function name, and disable the warning. For more information, see Turn off the warning and POSIX function names.
