The &func functions obtain information about an open file whose file
&handle is
.arg &fd..
This information is placed in the structure located at the address
indicated by
.arg buf.

.if &'length(&_func.) ne 0 .do begin
.np
The &_func function is identical to &func..
Use &_func for ANSI/ISO naming conventions.
.do end
The
.kw _fstati64,
.kw _wfstat,
and
.kw _wfstati64
functions differ from &func in the type of structure that they are
asked to fill in.
The
.kw _wfstat
and
.kw _wfstati64
functions deal with wide character strings.
The differences in the structures are described above.
