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 ‘\0
', rindex() locates the terminating ‘\0
'.
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.
