index(const
char *s, int
c);
index() function locates the first character
matching c (converted to a char) in
the nul-terminated string s.
This function is obsolete. The equivalent function strchr(3) should be used instead.
NULL is returned. If c is '\0',
index() locates the terminating '\0'.
index() 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
strchr(3) instead. The
IEEE Std 1003.1-2008 (“POSIX.1”)
revision removed index() from the specification.
index() function appeared in
Version 6 AT&T UNIX.
