where can I find the source code for strlen()?

Question

I know how to use this function, but now I want to know how it was written, I need the exact website or source code

Answer 1

I doubt you can find the exact source code, but my guess is all it does is start a counter at 0, start going through the string and counting characters until it hits the NULL terminator.

Something like this:

int strlen(char*)
{
int count = 0;
while (*(char + count) != 0)
{
count++;
if (count == 0xffffffff) //if max int size
break;
}
return (count);
