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 <ldap.h>
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() rou-
tines 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).
