The &func function writes output to the file designated by
.kw stdout
under control of the argument
.arg format.
The
.arg format
string is described below.

The &wfunc function is identical to &func except that it accepts a
wide-character string argument for
.arg format.

The &ufunc Unicode function is identical to &func except that it
accepts a Unicode string argument for
.arg format
and produces Unicode character output.
