According to Bruno Haible on 5/9/2008 8:20 PM:
| strndup is a glibc (not POSIX) function.
Not for long. It is on the list of functions being added in Posix 200x.
| I find the semantics of strndup,
| strnlen, and strncmp always hard to remember.
Particularly when competing against stpcpy and strlcpy.
| This complexity is not needed
| here: When you are extracting a substring, you already know that the string
| does not end before (str + len).
Good point. Therefore, a substring function can be more efficient than
strndup.
