putwchar(3) Library Functions Manual putwchar(3)

NAME top

   putwchar - write a wide character to standard output

LIBRARY top

   Standard C library (_libc_, _-lc_)

SYNOPSIS top

   **#include <wchar.h>**

   **wint_t putwchar(wchar_t** _wc_**);**

DESCRIPTION top

   The **putwchar**() function is the wide-character equivalent of the
   [putchar(3)](../man3/putchar.3.html) function.  It writes the wide character _wc_ to _stdout_.
   If _ferror(stdout)_ becomes true, it returns **WEOF**.  If a wide
   character conversion error occurs, it sets _[errno](../man3/errno.3.html)_ to **EILSEQ** and
   returns **WEOF**.  Otherwise, it returns _wc_.

   For a nonlocking counterpart, see [unlocked_stdio(3)](../man3/unlocked%5Fstdio.3.html).

RETURN VALUE top

   The **putwchar**() function returns _wc_ if no error occurred, or **WEOF**
   to indicate an error.

ATTRIBUTES top

STANDARDS top

   C11, POSIX.1-2008.

HISTORY top

   POSIX.1-2001, C99.

NOTES top

   The behavior of **putwchar**() depends on the **LC_CTYPE** category of the
   current locale.

   It is reasonable to expect that **putwchar**() will actually write the
   multibyte sequence corresponding to the wide character _wc_.
