Arguments:
type_: The type to reduce to its basic type.
Returns:
type_ with const/volatile is stripped away,
and typedefs/references converted to the underlying type.

Arguments:
type_: The type to examine.
It must be one of gdb.TYPE_CODE_STRUCT, gdb.TYPE_CODE_UNION.
field: The name of the field to look up.
Returns:
True if the field is present either in type_ or any baseclass.
Raises:
TypeError: The type is not a struct or union.

Wd S( s Return an iterator that recursively traverses anonymous fields.
Arguments:
type_: The type to traverse. It should be one of
gdb.TYPE_CODE_STRUCT or gdb.TYPE_CODE_UNION.
Returns:
an iterator similar to gdb.Type.iteritems(), i.e., it returns
pairs of key, value, but for any anonymous struct or union
field that field is traversed recursively, depth-first.

t TypePrinterc B s e Z d Z d Z d Z RS( s The base class for type printers.
Instances of this type can be used to substitute type names during
'ptype'.
A type printer must have at least 'name' and 'enabled' attributes,
and supply an 'instantiate' method.
The 'instantiate' method must either return None, or return an
object which has a 'recognize' method. This method must accept a
gdb.Type argument and either return None, meaning that the type
was not recognized, or a string naming the type.
