.SH DESCRIPTION
|
|
.LP
|
|
The \fIputwc\fP() function shall be equivalent to \fIfputwc\fP(),
|
|
except that if it is
|
|
implemented as a macro it may evaluate \fIstream\fP more than once,
|
|
so the argument should never be an expression with side
|
|
effects.
|
|
.SH RETURN VALUE
|
|
.LP
|
|
Refer to \fIfputwc\fP() .
|
|
.SH ERRORS
|
|
.LP
|
|
Refer to \fIfputwc\fP() .

.SH EXAMPLES

|
.LP
|
|
None.
|
|
.SH APPLICATION USAGE
|
|
.LP
|
|
Since it may be implemented as a macro, \fIputwc\fP() may treat a
|
|
\fIstream\fP 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\fP()
|
|
should be used instead.
|
|
