/*  File   : strrchr.c

    Author : Richard A. O'Keefe.

    Updated: 10 April 1984

    Defines: strrchr(), rindex()

    strrchr(s, c) returns a pointer to the  last  place  in  s	where  c

    occurs,  or  NullS if c does not occur in s. This function is called

    rindex in V7 and 4.?bsd systems; while not ideal the name is clearer

    than strrchr, so rindex  remains  in  strings.h  as  a  macro.   NB:

    strrchr  looks  for single characters, not for sets or strings.  The

    parameter 'c' is declared 'int' so it will go in a register; if your

    C compiler is happy with register char change it to that.
