Like strtok, it serves a niche purpose that doesn't come up as
often as people might think.

Yet it's actually strncat that is the odd one out of the trio...

  strncat(p, q, n) -  p is string, q is array
  strncmp(p, q, n) -  p is array,  q is array
  strncpy(p, q, n) -  p is array,  q is array

If they were prefixed memn, instead of strn, then I'm reasonably
sure there would be fewer complaints and surprises with strncpy.

The problem with strncpy is not that it pads with zero or won't
terminate a full array. The problem is that it doesn't let you
choose the pad character.
