Hello, I faced a problem some time back on a particular website. It has given many hyperlinks on it to other sites. e.g. of one such URL is: http://http//example.com/a9noaa.asp It is clearly incorrect (http comes twice) URL so when one clicks on it there is a page error like "Address not found".

Is the following code a sane way to store it? uint64_t size = 0; // ... getBytes((uint32_t*)&size+0x1); I'm assuming that this would be the canonical, safe style: ui...
