 LDAP_FIRST_ATTRIBUTE 3LDAP "May 13, 2017"
 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.
 ATTRIBUTES

See attributes(5) for a description of the following attributes:
