LDAP_FIRST_ATTRIBUTE(3) LDAP_FIRST_ATTRIBUTE(3)
NAME
ldap_first_attribute, ldap_next_attribute - step through LDAP entry attributes
LIBRARY
OpenLDAP LDAP (libldap, -lldap)
SYNOPSIS
#include
char *ldap_first_attribute(
LDAP *ld, LDAPMessage entry, BerElement **berptr )
char *ldap_next_attribute(
LDAP *ld, LDAPMessage entry, BerElement *ber )
DESCRIPTION
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 con-
taining 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).
