_putch, _putwch

Writes a character to the console.

int _putch(
   int c 
);
wint_t _putwch(
   wchar_t c
);

Parameters

  • c
    Character to be output.

Return Value

Returns c if successful. If _putch fails, it returns EOF; if _putwch fails, it returns WEOF.

Remarks

These functions write the character c directly, without buffering, to the console. In Windows NT, _putwch writes Unicode characters using the current console locale setting.

The versions with the _nolock suffix are identical except that they are not protected from interference by other threads. For more information, see _putch_nolock, _putwch_nolock.
