_putch, _putwch

  • Artikel

Writes a character to the console.

Important

This API cannot be used in applications that execute in the Windows Runtime. For more information, see CRT functions not supported in Universal Windows Platform apps.

Syntax

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 aren't protected from interference by other threads. For more information, see _putch_nolock, _putwch_nolock.

By default, this function's global state is scoped to the application. To change this behavior, see Global state in the CRT.

Generic-text routine mappings

Requirements
