It writes the wide-character string starting at \fIws\fP, up to but not including the terminating null wide character (L\[aq]\e0\[aq]), to \fIstream\fP. .PP For a nonlocking counterpart, see .BR unlocked_stdio (3). .SH RETURN VALUE The .BR fputws () function returns a nonnegative integer if the operation was successful, or \-1 to indicate an error. .SH ATTRIBUTES For an explanation of the terms used in this section, see .BR attributes (7). .TS allbox; lbx lb lb l l l.
