INDEX(3) Linux Programmer's Manual INDEX(3)NAME
index, rindex - locate character in string
SYNOPSIS
#include <strings.h>
char *index(const char *s, int c);
char *rindex(const char *s, int c);
DESCRIPTION
The index() function returns a pointer to the first occurrence of the character c in the string s.
The rindex() function returns a pointer to the last occurrence of the character c in the string s.
The terminating null byte (' ') is considered to be a part of the strings.
RETURN VALUE
The index() and rindex() functions return a pointer to the matched character or NULL if the character is not found.
CONFORMING TO
4.3BSD; marked as LEGACY in POSIX.1-2001. POSIX.1-2008 removes the specifications of index() and rindex(), recommending strchr(3) and str-
rchr(3) instead.
