Function : Basic Encoding Rules

ber_next_element - Used to traverse a set or sequence of data values.

#include <lber.h>
ber_tag_t LNPUBLIC ber_next_element(

    BerElement *ber,
    ber_len_t *len,
    char *last);

Description :

This routine is used, along with ber_first_element(), to traverse a set or sequence of data values.

The ber_first_element() function is used to return the tag of the first element of a set or sequence of data values. It also returns the last byte of a set or sequence of data values. This "last" parameter should be passed to subsequent calls to ber_next_element(), which returns similar information, namely the tag of the next element to be parsed and the last element in a set or sequence of data values.

Implemented as a macro:

define ber_next_element(ber, len, last) ND_ber_next_element((ber), (len),

(last))

Parameters : Input : ber - This state pointer points at the start of the next element to be parsed.

len - The length of the element to be parsed.

Output : (routine) - Returns the tag of the next element to be parsed. LBER_DEFAULT is returned if there are no further values.

last - The last element in a set or sequence of data values.
