class CFile :public virtual IFile
    {
    public:
        String getFilename() override;
        long long getSize() override;
        long long getPointer() override;
    
        bool setPointer(const long long value, const SEEK_FROM seek_from) override;
    
        bool Read(const unsigned int size, unsigned char *buffer, unsigned long &read) override;
        bool Write(const unsigned int size, unsigned char *buffer, unsigned long &written) override;
    
        void Release() override;
    
        CFile(FILE *file, const String &filename);
        virtual ~CFile() = default;
    };
