getchar, getwchar
Read a character from standard input.
int getchar(); wint_t getwchar();
Each routine reads a single character from stdin and increments the associated file pointer to point to the next character. getchar is the same as _fgetchar, but it is implemented as a function and as a macro.
These functions lock the calling thread and are therefore thread-safe. For a non-locking version, see _getchar_nolock, _getwchar_nolock.

The console is not supported in Windows Store apps. The standard stream handles associated with the console, stdin, stdout, and stderr, must be redirected before C run-time functions can use them in Windows Store apps. For additional compatibility information, see Compatibility in the Introduction.
