Furthermore, the index/strchr difference is probably not an example of NIH
in the way the original poster thought.  *Both* routines are products of
AT&T - the routine was called "index" in V7 and "strchr" in System III.  At
what point it was renamed, I dunno.  The S3 documentation comes with a
description of changes between S3 and some unspecified earlier version of
UNIX.  One of the changes was that "strcpyn" was renamed "strncpy".  This
predates V7, since it was called "strncpy" there as well.
