write(contentsOf:)

Writes the specified data synchronously to the file handle.

Declaration 宣言 

func write<T>(contentsOf data: T) throws where T : DataProtocol

Parameters パラメータ

data

The data to write to the file handle.

Discussion 議論

If the handle represents a file, writing takes place at the file pointer’s current position. After it writes the data, the method advances the file pointer by the number of bytes written. それがデータを書き出す後、メソッドはファイルポインタを書き出されたバイト数だけ前進させます。 This method throws an error if the file descriptor is closed or isn’t valid, if the handle represents an unconnected pipe or socket endpoint, if there isn’t any free space on the file system, or if any other writing error occurs.
