INDEX(3)			   BSD Library Functions Manual 			 INDEX(3)

NAME
     index -- locate character in string

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <strings.h>

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

DESCRIPTION
     The index() function locates the first 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', index() locates the terminating '\0'.

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

STANDARDS
     The 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 specifi-
     cation.

HISTORY
     An index() function appeared in Version 6 AT&T UNIX.
