STRRCHR(3)

NAME
strrchr, rindex - locate last occurrence of a character in a string

SYNOPSIS
#include <string.h>
char *
strrchr(const char *s, int c);
#include <strings.h>
char *
rindex(const char *s, int c);

DESCRIPTION
The strrchr() function locates the last occurrence of the character c (converted to a char) in the string s. The terminating NUL character is considered part of the string. If c is ‘\0’, strrchr() locates the terminating ‘\0’.

The rindex() function is an old synonym for strrchr().

RETURN VALUES
The strrchr() function returns a pointer to the located character or NULL if the character does not appear in the string.

EXAMPLES
After the following call to strrchr(), p will point to the string "obar":

    char *p;
    char *s = "foobar";
    p = strrchr(s, 'o');

STANDARDS
The strrchr() function conforms to ansiC.

The rindex() function is deprecated and shouldn't be used in new code.

HISTORY
The rindex() function first appeared in AT&T UNIX. The strrchr() function first appeared in AT&T UNIX III and was reimplemented for 4.3BSD.
