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() function. It writes the wide character wc to stdout. If fer‐
ror(stdout) becomes true, it returns WEOF. If a wide character conver‐
sion error occurs, it sets errno to EILSEQ and returns WEOF. Otherwise
it returns wc.
For a non-locking counterpart, see unlocked_stdio(3).
RETURN VALUE
The putwchar() function returns wc if no error occurred, or WEOF to
indicate an error.
CONFORMING TO
C99.
NOTES
The behaviour 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.
