It may evaluate 73.Fa stream 74more than once, so arguments given to 75.Fn putwc 76should not be expressions with potential side effects. 77.Pp 78.Fn putwchar 79is identical to 80.Fn putwc 81with an output stream of 82.Em stdout . 83.Sh RETURN VALUES 84The functions, 85.Fn fputwc , 86.Fn putwc 87and 88.Fn putwchar 89return the wide-character written. 90If an error occurs, the value 91.Dv WEOF 92is returned. 93.Sh SEE ALSO 94.Xr ferror 3 , 95.Xr fopen 3 , 96.Xr getwc 3 , 97.Xr stdio 3 98.Sh STANDARDS 99The functions 100.Fn fputwc , 101.Fn putwc , 102and 103.Fn putwchar , 104conform to 105.St -isoC-99 . 106
