Thread: Curropted text

Turns out memcpy does not do what is says on the tin, replaced it with this:

Code:

txt = (char*)(tok.dst.addr);
for ( byte = 0; byte < size; ++byte, ++txt ) txt[byte] = cb[byte];

and hay presto I have correct text, remind me never to expect common sense in the standard library

That's likely because you used memcpy in an undefined way (e.g., source and destination overlap). I haven't looked too deeply at your code to see if that's the case, but there's an exceedingly low chance (like one in a million) that a standard library function is at fault.

Nope, that scenario is already ruled out by prior code, besides if that had been the issue then the loop I made would have encountered the exact same issue
