+.SH NAME
+putwc
+\(em put a wide character on a stream
+.SH SYNOPSIS
+.LP
+.nf
+#include <stdio.h>
+#include <wchar.h>
+.P
+wint_t putwc(wchar_t \fIwc\fP, FILE *\fIstream\fP);
+.fi
+.SH DESCRIPTION
+The functionality described on this reference page is aligned with the
+ISO\ C standard. Any conflict between the requirements described here and the
+ISO\ C standard is unintentional. This volume of POSIX.1\(hy2017 defers to the ISO\ C standard.
+.P
+The
+\fIputwc\fR()
+function shall be equivalent to
+\fIfputwc\fR(),
+except that if it is implemented as a macro it may evaluate
+.IR stream
+more than once, so the argument should never be an expression with
+side-effects.
+.SH "RETURN VALUE"
+Refer to
+.IR "\fIfputwc\fR\^(\|)".
+.SH ERRORS
+Refer to
+.IR "\fIfputwc\fR\^(\|)".
+.LP
+.IR "The following sections are informative."
+.SH EXAMPLES
+None.
+.SH "APPLICATION USAGE"
+Since it may be implemented as a macro,
+\fIputwc\fR()
+may treat a
+.IR stream
+argument with side-effects incorrectly. In particular,
+\fIputwc\fP(\fIwc\fP,*\fIf\fP++) need not work correctly. Therefore,
+use of this function is not recommended;
+\fIfputwc\fR()
+should be used instead.
+.SH RATIONALE
+None.
+.SH "FUTURE DIRECTIONS"
+None.
+.SH "SEE ALSO"
