ldap_first_attribute, ldap_next_attribute - step through LDAP entry attributes
OpenLDAP LDAP (libldap, -lldap)
#include <ldap.h>
char *ldap_first_attribute(
LDAP *ld, LDAPMessage *entry, BerElement **berptr )
char *ldap_next_attribute(
LDAP *ld, LDAPMessage *entry, BerElement *ber )
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 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.
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.
The ldap_first_attribute() and ldap_next_attribute() return
dynamically allocated memory that must be freed by the caller via
ldap_memfree(3).
