LDAP_FIRST_ATTRIBUTE(3) Library Functions Manual LDAP_FIRST_ATTRIBUTE(3)
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).
