PUTWCHAR(3) Linux Programmer's Manual PUTWCHAR(3)

NAME

     putwchar - write a wide character to standard output

SYNOPSIS

     #include <wchar.h>

     wint_t putwchar(wchar_t wc);

DESCRIPTION

     The  putwchar()  function  is  the  wide-character  equivalent  of  the
     putchar(3) function.  It writes the wide character wc  to  stdout.   If
     ferror(stdout) becomes true, it returns WEOF.  If a wide character con-
     version error occurs, it sets errno to EILSEQ and returns WEOF.  Other-
     wise, it returns wc.

     For a nonlocking counterpart, see unlocked_stdio(3).

RETURN VALUE

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

CONFORMING TO

     POSIX.1-2001, POSIX.1-2008, C99.

NOTES

     The behavior of putwchar() depends on the LC_CTYPE category of the cur-
     rent locale.

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