The
ldap_first_attribute()
and
ldap_next_attribute()
routines are used
to step through the attributes in an LDAP entry.
ldap_first_attribute()
takes an entry as returned by
ldap_first_entry(3)
or
ldap_next_entry(3)
and returns a pointer to character string
containing the first attribute description in the entry.
ldap_next_attribute()
returns the next attribute description in the entry.
It also returns, in berptr, a pointer to a BerElement it has
allocated to keep track of its current position. This pointer should
be passed to subsequent calls to
ldap_next_attribute()
and is used used
to effectively step through the entry's attributes. The caller is
solely responsible for freeing the BerElement pointed to by berptr
when it is no longer needed by calling
ber_free(3).
When calling
ber_free(3)
in this instance, be sure the second argument is 0.
The attribute names returned are suitable for inclusion in a call
to
ldap_get_values(3)
to retrieve the attribute's values.
ERRORS
If an error occurs, NULL is returned and the ld_errno field in the
ld parameter is set to indicate the error. See
ldap_error(3)
for a description of possible error codes.
NOTES
The
ldap_first_attribute()
and
ldap_next_attribute()
return dynamically allocated memory that must be freed by the caller via
ldap_memfree(3).
