rindex

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 nul-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)

STANDARDS

     The rindex() function conforms to IEEE Std 1003.1-2001 (``POSIX.1'').  The IEEE Std 1003.1-2004 (``POSIX.1'') revision marked it as legacy
     and recommended the use of strrchr(3) instead.  The IEEE Std 1003.1-2008 (``POSIX.1'') revision removed rindex() from the specification.

HISTORY

     A rindex() function appeared in Version 6 AT&T UNIX.
