nn::fs::FileStream Class

Syntax

class FileStream : 
    private nn::fs::IStream,
    private nn::fs::detail::FileBase,
    private ADLFireWall::NonCopyable

Description

Class for reading from and writing to files.

Can open the file specified by a path name and read and write data from and to it.

Although it is possible to use either wide-character strings or multibyte-character strings to specify the path name, use wide-character strings unless you have a special reason to do otherwise.

This class cannot be used to create new files in expanded save data. For that, use a TryCreateFile function that specifies the size.
