 is not a filename but rather a file handle name, a FileHandle object,
 or a file descriptor number.
 
+If the C functions fgetpos() and fsetpos() are available, then
+C<FileHandle::getpos> returns an opaque value that represents the
+current position of the FileHandle, and C<FileHandle::setpos> uses
+that value to return to a previously visited position.
+
+If the C function setvbuf() is available, then C<FileHandle::setvbuf>
+sets the buffering policy for the FileHandle.  The calling sequence
+for the Perl function is the same as its C counterpart, including the
+macros C<_IOFBF>, C<_IOLBF>, and C<_IONBF>, except that the buffer
+parameter specifies a scalar variable to use as a buffer.  WARNING: A
+variable used as a buffer by C<FileHandle::setvbuf> must not be
+modified in any way until the FileHandle is closed or until
+C<FileHandle::setvbuf> is called again, or memory corruption may
+result!

 See L<perlfunc> for complete descriptions of each of the following
 supported C<FileHandle> methods, which are just front ends for the
 corresponding built-in functions:
