Hi<br />
<br />
in the write line, what does this mean?<br />
(char*)&amp;o1<br />
<br />
Is this the normally used way to write to file today, it seems a little DOS'ed<br />
<br />
<br />
Can you explain me how this works<br />
<br />
reinterpret_cast&lt;char * &gt;( &amp;x[1] )<br />
<br />
x: array of char
