The standard string library is still pretty bad. This would have been a much better addition for safe strcpy.

Safe strcpy

    char *stecpy(char *d, const char *s, const char *e)
    {
     while (d < e && *s)
      *d++ = *s++;
     if (d < e)
      *d = '\0';
     return d;
    }

    main() {
      char buf[64];
      char *ptr, *end = buf+sizeof(buf) ;

      ptr = stecpy(buf, "hello", end);
      ptr = stecpy(ptr, " world", end);
    }

Existing solutions are still error-prone, requiring continual recalculation of buffer len after each use in a long sequence, when the only thing that matters is where the buffer ends, which is effectively a constant across multiple calls.

What are the chances of getting something like this added to the standard library?
