:: Function # call(*args) -> Integer|DL :: CPtr|nil (21262.0) -
関数を呼び出します。
...関数を呼び出します。
Fiddle::Function.new で指定した引数と返り値の型に基いて
Ruby のオブジェクトを適切に C のデータに変換して C の関数を呼び出し、
その返り値を Ruby のオブジェクトに変換して返します。
引数の変換は....../int/long/long long
Ruby の整数を C の整数に変換します。
: double/float
Ruby の整数 or 浮動小数点数を C の浮動小数点数に変換します
返り値の変換は以下の通りです。
: void
nil を返します
: (unsigned) char/short/int/long/long long
C......の整数を Ruby の整数に変換します
: void*(つまり任意のポインタ型)
C のポインタを保持した Fiddle::Pointer を返します。

Module
# ruby2 _ keywords(method _ name , . . . ) -> nil (12411.0) -
For the given method names, marks the method as passing keywords through a normal argument splat. This should only be called on methods that accept an argument splat (`*args`) but not explicit keywords or a keyword splat. It marks the method such that if the method is called with keyword arguments, the final hash argument is marked with a special flag such that if it is the final element of a normal argument splat to another method call, and that method call does not include explicit keywords or a keyword splat, the final element is interpreted as keywords. In other words, keywords will be passed through the method to other methods.

Exception
# full _ message(highlight: true , order: :bottom) -> String (3137.0) -
例外の整形された文字列を返します。
...例外の整形された文字列を返します。
返される文字列は Ruby が捕捉されなかった例外を標準エラー出力に出力するときと
同じ形式です。
そのため、メソッド呼び出し時に $stderr が変更されておらず、$stderr.tty? が真の場合......Exception.to_tty? の返り値と同じです。
@param order :top か :bottom で指定する必要があります。
バックトレースの一番奥がエラーメッセージの上(top)か下(bottom)かを指定します。
デフォルト値は Exception.to_tty? が......真なら :bottom で偽なら :top です。
