Character Manipulation Function

int _getche(void);

wint_t _getwche(void);

_TINT _gettche(void);

Internationalization (I18n) Function Overview

The _getche function reads a character from the console, echoing the character.

_getwche is the wide-character version of _getche, returning a wide-character wint_t.

_gettche is the Generic version of the function; with the _MBCS or _UNICODE compiler flags determining its mapping to either _getche or _getwche.

These functions cannot be used to read CTRL+C. In addition, _getche will need to be called twice when reading a function key or an arrow key, with the first call returning 0 or 0xE0, and the second call returning the actual key code.

I18n Issues

Use the appropriate version of the function as required for internationalization support.

See Character I/O for a discussion on non-ASCII character input/output in an internationalized application.
