RINDEX(3)						   BSD Library Functions Manual 						 RINDEX(3)

NAME

     rindex -- locate character in string

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <strings.h>

     char *
     rindex(const char *s, int c);

DESCRIPTION

     The rindex() function locates the last character matching c (converted to a char) in the null-terminated string s.

RETURN VALUES

     A pointer to the character is returned if it is found; otherwise, NULL is returned.  If c is '', rindex() locates the terminating ''.

SEE ALSO

     index(3), memchr(3), strchr(3), strcspn(3), strpbrk(3), strrchr(3), strsep(3), strspn(3), strstr(3), strtok(3)

HISTORY

     A rindex() function appeared in Version 6 AT&T UNIX.  Its prototype existed previously in <string.h> before it was moved to <strings.h> for
     IEEE Std 1003.1-2001 (``POSIX.1'') compliance.

NAME

     index, rindex -- locate character in string

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <strings.h>

     char *
     index(const char *s, int c);

     char *
     rindex(const char *s, int c);

DESCRIPTION

     The index() function locates the first occurrence of c (converted to a char) in the string pointed to by s.  The terminating null character
     is considered to be part of the string; therefore, if c is '', the functions locate the terminating ''.

     The rindex() function is identical to index(), except that it locates the last occurrence of c.

RETURN VALUES

     The functions index() and rindex() return a pointer to the located character, or NULL if the character does not appear in the string.

SEE ALSO

     memchr(3), strchr(3), strcspn(3), strpbrk(3), strrchr(3), strsep(3), strspn(3), strstr(3), strtok(3)

HISTORY

     The index() and rindex() functions appeared in Version 6 AT&T UNIX.  Their prototypes existed previously in <string.h> before they were moved
     to <strings.h> for IEEE Std 1003.1-2001 (``POSIX.1'') compliance.
