/*  File   : strstr.c

    Author : Monty

    Updated: 1986.11.24

    Defines: strstr()

    strstr(src, pat) looks for an instance of pat in src.  pat is not a

    regex(3) pattern, it is a literal string which must be matched exactly.

    The result is a pointer to the first character of the located instance,

    or NullS if pat does not occur in src.
