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() 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.

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).
