(LISP-SYM CPP-MACRO)
...)
(define-flags FLAGS-TYPEDEF-NAME
(LISP-SYM CPP-MACRO)

(define-boxed BOXED-TYPEDEF-NAME

where each ATTR is one of:
(copy C-COPY-FUN)
(free C-FREE-FUN)
(size "C sizeof expression")
(fields FIELD ...)
where each FIELD is (TYPE-SYM NAME-SYM OPTIONS...)
each OPTION may be `(setter t)' denoting that the field
is settable. Also `(getter FUNCTION-NAME)' defining a custom
method of retrieving the value
(define-object OBJECT-TYPEDEF-NAME (SUPER-CLASS-TYPEDEF)
ATTR ...)
where each ATTR is one of:
(fields FIELD ...) [as above]
(define-func C-FUNC-NAME
RETURN-VALUE [RET-OPTIONS...]
(ARG ...)
OPTIONS...)
where each ARG is (TYPE NAME-SYM [ARG-OPTIONS...)
and each OPTION may be one of:
(scm-name ACTUAL-NAME-STRING)
(protection ARG) ; gc protect callback for life of ARG
(protection t) ; gc protect callback always
(protection *result*) ; gc protect for life of RETURN-VALUE
(undeferred t) ; no scm interrupt protection?
(rest-arg t) ; last arg is &rest
(gerror-arg t) ; last arg is GError arg
and each ARG-OPTION may be one of:
(= "default expression")
(null-ok) ; allow nil
(protect-during)
and each RET-OPTION may be one of:
(copy nil) ; unimplemented?
(options OPTION ...)
where each OPTION can be:
(includes "#include expression")
(init-func "name of C function")
(other-inits "name of C function" ... )
(extra-init-code "code string")
(provide FEATURE)
the `provide' option generates the rep dl stub required to provide
FEATURE and call the init-func when loaded
GTK fundamental types seem to include:
invalid, none, char, bool, int, uint, long, ulong, float,
string, enum, flags, boxed, foreign, callback, args, pointer,
signal, c-callback, object
static_string:
a static string returned from a function
full_callback:
a callback function used by the _full function variants (i.e.
gtk_signal_connect_full).
file-descriptor:
an integer file descriptor
double:
a double-precision float
SCM:
a scheme object
(list TYPE [MODE]):
a glib GList* (doubly-linked)
(slist TYPE [MODE]):
a glib GSList* (singly-linked)
(cvec TYPE [MODE]):
a counted-vector, stored in sgtk_cvec struct, in gtk_ function calls,
it expands ``cvec.data, cvec.len''
(cvecr TYPE [MODE]):
similar to cvec but expands ``cvec.len, cvec.data''
(fvec TYPE LEN [MODE]):
similar to cvec but fixed length
(ret TYPE):
similar to fvec but length is always one. used to mimic the C ``&foo''
idiom of returning multiple values
(tvec TYPE [MODE]):
zero-terminated vector
[ in the above, MODE is one of `in', `out' or `inout'. Defaults to `in' ]
