class SafeData

내가 이딴건 왜 만들었을까...

class SafeData {

    SafeData();
    virtual ~SafeData();
    void SetByCopy( Data inData );

    uint8 *GetData();
    int GetLength();
    void Clear();
    
protected:
    uint8 *pBuffer;
    int length;
};

SafeData::SafeData()
{
    pBuffer = NULL;
    length = 0;
};

{
    Clear();
};

void SafeData::SetByCopy( Data inData )
{
    Clear();
    pBuffer = new uint8[inData.len];
    if( pBuffer==NULL )
        return;
    length = inData.len;
    memcpy( pBuffer, inData.d, length );
}

    Clear();
    pBuffer = new uint8[l];
    if( pBuffer==NULL )

{

    pBuffer = d;

}

uint8 *SafeData::GetData() {return pBuffer;}
