RINDEX(3)               NetBSD 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.

     This function is obsolete.  The equivalent function strrchr(3) should be
     used instead.


RETURN VALUES

     A pointer to the character is returned if it is found; otherwise NULL is
     returned.  If c is `\0', rindex() locates the terminating `\0'.


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.
