LDAP_FIRST_ATTRIBUTE(3LDAP) LDAP Library Functions

NAME

ldap_first_attribute, ldap_next_attribute - step through LDAP entry
attributes

SYNOPSIS

cc [ flag...] file... -lldap[ library...]
#include <lber.h>
#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() function gets the value of the first
attribute in an entry.


The ldap_first_attribute() function returns the name of the first
attribute in the entry. To get the value of the first attribute, pass
the attribute name to the ldap_get_values() function or to the
ldap_get_values_len() function.


The ldap_next_attribute() function gets the value of the next
attribute in an entry.


After stepping through the attributes, the application should call
ber_free() to free the BerElement structure allocated by the
ldap_first_attribute() function if the structure is other than NULL.

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(3LDAP) for a
description of possible error codes.

NOTES

The ldap_first_attribute() function allocates memory that might need
to be freed by the caller by means of ber_free(3LDAP).
