Did you read the rest of the answer?
It's "somewhat obscure" because it's not immediately clear why you cannot do that, so it requires a bit of explanation. That explanation is contained on that page that you linked to.
If you don't know, don't comment.
I suppose, safety..
Since you seem to just be trolling people, can you explain why this code doesn't work?
Hope you don't find too much that is abhorrent in there :DCode:int my_strlen(char *s) {
char *a = s;
while(1) {
s++;
if(s[-1] == '\0')
break;
}
// A non-MIRSA 2004 compliant comment, just for fun.
return s-a-1;
}

I assure you, work is being done.
So you are wrong..
So yes these post are relevant.
They may not be relevant to you, because you can't see my documents.
That's all.
Who says I don't know? I explained exactly why it says the reason is "somewhat obscure"!Quote:

I've never seen the term "Help Vampire" before...Quote:

Are you saying that that code actually works (and returns the length of the s parameter)?Quote:

Similarly, one may mistake a cursive handwriting with sharpness and mastery,
Even if it seems conventional and accepted, this a serious contradiction,
By removing style from a handwriting, the handwriting becomes readable and excellent.
This is what you fail to realize.
