strrchr, rindex - locate last occurrence of a character in a
string
#include <string.h>
char *
strrchr(const char *s, int c);
char *
rindex(const char *s, int c);
The strrchr() function locates the last occurrence of the
character c in
the string s. The terminating NUL character is considered
part of the
string. If c is ` ', strrchr() locates the terminating ` '.
The rindex() function is an old synonym for strrchr().
The strrchr() function returns a pointer to the located
character or NULL
if the character does not appear in the string.
After the following call to strrchr(), p will point to the
string "obar":
char *p;
char *s = "foobar";
p = strrchr(s, 'o');

The strrchr() function conforms to ANSI X3.159-1989 (``ANSI
C'').
The rindex() function is deprecated and shouldn't be used in
new code.
