    NAME

    fputwc, putwc - write a wide character to a FILE stream
     
    

    SYNOPSIS

    #include <stdio.h>
    
    #include <wchar.h> wint_t fputwc(wchar_t wc, FILE *stream); wint_t putwc(wchar_t wc, FILE *stream);
     

    DESCRIPTION

    The fputwc() function is the wide-character equivalent of the fputc(3) function. It writes the wide character wc to stream. If ferror(stream) becomes true, it returns WEOF. If a wide-character conversion error occurs, it sets errno to EILSEQ and returns WEOF. Otherwise it returns wc.

    The putwc() function or macro functions identically to fputwc(). It may be implemented as a macro, and may evaluate its argument more than once. There is no reason ever to use it.

    For non-locking counterparts, see unlocked_stdio(3).  

    RETURN VALUE

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

    ERRORS

    Apart from the usual ones, there is
    EILSEQ
    Conversion of wc to the stream's encoding fails.
     

    CONFORMING TO

    C99, POSIX.1-2001.  

    NOTES

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

    In the absence of additional information passed to the fopen(3) call, it is reasonable to expect that fputwc() will actually write the multibyte sequence corresponding to the wide character wc.
