Who would use a null-terminated string for anything in a C++ program?
Here's a handy idiom:

  template <unsigned N>
    int f(const char (&a)[N])
      { return ::write(1, a, N-1); }

  int main() { return f("abc\n"); }

The template engine deduces the size of the literal string and binds N
to that value, so you don't need to search for any dumb terminator.
Better yet, if you call f with a pointer, the compiler rejects it.
