It may evaluate 72.Fa stream 73more than once, so arguments given to 74.Fn putwc 75should not be expressions with potential side effects. 76.Pp 77.Fn putwchar 78is identical to 79.Fn putwc 80with an output stream of 81.Em stdout . 82.Sh RETURN VALUES 83The functions, 84.Fn fputwc , 85.Fn putwc 86and 87.Fn putwchar 88return the wide-character written. 89If an error occurs, the value 90.Dv WEOF 91is returned. 92.Sh SEE ALSO 93.Xr ferror 3 , 94.Xr fopen 3 , 95.Xr getwc 3 , 96.Xr stdio 3 97.Sh STANDARDS 98The functions 99.Fn fputwc , 100.Fn putwc , 101and 102.Fn putwchar , 103conform to 104.St -isoC99 . 105
