Get a character from the console without echo (_getch) or with echo (_getche).
| #include <conio.h> | Required only for function declarations |
int _getch( void );
int _getche( void );
The _getch function reads a single character from the console without echoing. The _getche function reads a single character from the console and echoes the character read. Neither function can be used to read CTRL+C.
When reading a function key or cursor-moving key, the _getch and _getche functions must be called twice; the first call returns 0 or 0xE0, and the second call returns the actual key code.
Both the _getch and _getche functions return the character read. There is no error return.
