.desc begin
The &func function writes the character specified by the argument
.arg c
to the output stream
.kw stdout.
.pp
The function is equivalent to
.millust begin
fputc( c, stdout );
.millust end
.if &'length(&wfunc.) ne 0 .do begin
.np
The &wfunc function is identical to &func except that it converts the
wide character specified by
.arg c
to a multibyte character and writes it to the output stream.
.do end
.if &'length(&ufunc.) ne 0 .do begin
.np
The &ufunc Unicode function is identical to &func except that it
accepts a Unicode character argument
.arg c
and writes the Unicode character to the output stream.
.do end
.desc end
.return begin
The &func function returns the character written or, if a write error
occurs, the error indicator is set and &func returns
.kw EOF.
.if &'length(&wfunc.) ne 0 .do begin
.np
The &wfunc function returns the wide character written or, if a write
error occurs, the error indicator is set and &wfunc returns
.kw WEOF.
