@ -2303,14 +2303,6 @@ A pointer to a NUL terminated string: the name of the port type. This
is the only element of @code{scm_ptob_descriptor} which is not
a procedure. Set via the first argument to @code{scm_make_port_type}.
@item mark
Called during garbage collection to mark any SCM objects that a port
object may contain. It doesn't need to be set unless the port has
@code{SCM} components. Set using
@deftypefun void scm_set_port_mark (scm_t_bits tc, SCM (*mark) (SCM port))
@end deftypefun
@item free
Called when the port is collected during gc. It
should free any resources used by the port.
