オブジェクトのインスタンス変数名をシンボルの配列として返します。
...列として返します。

そのモジュール(またはクラス)で定義されている定数名の配列を返します。
...クルードしているモジュールの定数も含みます。
Object のサブクラスの場合、Objectやそのスーパークラスで定義されている
定数は含まれません。 Object.constants とすると Object クラスで定義された
定数の配列が得られます。......dule.constants, Kernel.#local_variables, Kernel.#global_variables, Object#instance_variables, Module#class_variables

Returns the convertible integer type of the given +type+. You may optionally specify additional +headers+ to search in for the +type+. _Convertible_ means actually same type, or typedefed from same type. If the +type+ is a integer type and _convertible_ type is found, following macros are passed as preprocessor constants to the compiler using the +type+ name, in uppercase. * 'TYPEOF_', followed by the +type+ name, followed by '=X' where 'X' is the found _convertible_ type name. * 'TYP2NUM' and 'NUM2TYP, where 'TYP' is the +type+ name in uppercase with replacing '_t' suffix with 'T', followed by '=X' where 'X' is the macro name to convert +type+ to +Integer+ object, and vice versa. For example, if foobar_t is defined as unsigned long, then convertible_int("foobar_t") would return "unsigned long", and define macros: #define TYPEOF_FOOBAR_T unsigned long #define FOOBART2NUM ULONG2NUM #define NUM2FOOBART NUM2ULONG
