virtual unsigned int XmlInputStream::readBytes(
    char *toFill, const unsigned int maxToRead)
      
        Reads maxToRead number of bytes from the input 
        stream and places those bytes in toFill. Returns 
        the number of bytes read, or 0 if the end of the stream has been 
        reached.   
    
Specifies a pointer to a buffer used to place the bytes read from the input stream. It is the responsibility of the programmer to ensure that the buffer provided here is large enough for the amount of data to be read.
