NAME

       index - character string operations (LEGACY)

SYNOPSIS

       #include <strings.h>

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

DESCRIPTION

       The index() function shall be equivalent to strchr().

RETURN VALUE

       See strchr() .

ERRORS

       See strchr() .

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       The strchr() function is preferred over this function.

       For maximum portability, it is recommended to replace the function call to index() as follows:

	      #define index(a,b) strchr((a),(b))

RATIONALE

       None.

FUTURE DIRECTIONS

       This function may be withdrawn in a future version.
