23.4.5.2 Guile Types Module

This module provides a collection of utilities for working with <gdb:type> objects.

Usage:

(use-modules (gdb types))

Scheme Procedure: get-basic-type type

Return type with const and volatile qualifiers stripped, and with typedefs and C++ references converted to the underlying type.

C++ example:

typedef const int const_int;
const_int foo (3);
const_int& foo_ref (foo);
int main () { return 0; }

Then in gdb:

(gdb) start
(gdb) guile (use-modules (gdb) (gdb types))
(gdb) guile (define foo-ref (parse-and-eval "foo_ref"))
(gdb) guile (get-basic-type (value-type foo-ref))
int

Scheme Procedure

type-has-field-deep? type field

Return #t if type, assumed to be a type with fields (e.g., a structure or union), has field field. Otherwise return #f. This searches baseclasses, whereas type-has-field? does not.

Scheme Procedure

make-enum-hashtable enum-type

Return a Guile hash table produced from enum-type. Elements in the hash table are referenced with hashq-ref.
