NAME         top

       ldap_first_attribute, ldap_next_attribute - step through LDAP
       entry attributes

LIBRARY         top

       OpenLDAP LDAP (libldap, -lldap)

SYNOPSIS         top

       #include <ldap.h>

       char *ldap_first_attribute(
            LDAP *ld, LDAPMessage *entry, BerElement **berptr )

       char *ldap_next_attribute(
            LDAP *ld, LDAPMessage *entry, BerElement *ber )

DESCRIPTION         top

       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         top

       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         top

       The ldap_first_attribute() and ldap_next_attribute() return
       dynamically allocated memory that must be freed by the caller via
       ldap_memfree(3).
