_getche, _getwche

Gets a character from the console with echo.

int _getche( void );
wint_t _getwche( void );

Returns the character read. There is no error return.

The _getche and_getwche functions read a single character from the console with echo, meaning that the character is displayed at the console. None of these functions can be used to read CTRL+C. When reading a function key or an arrow key, each function must be called twice; the first call returns 0 or 0xE0, and the second call returns the actual key code.

These functions lock the calling thread and are therefore thread-safe. For non-locking versions, see _getche_nolock, _getwche_nolock.
