Описание (Description)
These routines are used to retrieve and manipulate attribute
values from an LDAP entry as returned by ldap_first_entry(3) or
ldap_next_entry(3). ldap_get_values() takes the entry and the
attribute attr whose values are desired and returns a NULL-
terminated array of the attribute's values. attr may be an
attribute type as returned from ldap_first_attribute(3) or
ldap_next_attribute(3), or if the attribute type is known it can
simply be given.
The number of values in the array can be counted by calling
ldap_count_values(). The array of values returned can be freed
by calling ldap_value_free().
If the attribute values are binary in nature, and thus not
suitable to be returned as an array of char *'s, the
ldap_get_values_len() routine can be used instead. It takes the
same parameters as ldap_get_values(), but returns a NULL-
terminated array of pointers to berval structures, each
containing the length of and a pointer to a value.
The number of values in the array can be counted by calling
ldap_count_values_len(). The array of values returned can be
freed by calling ldap_value_free_len().
Ошибки (Error)
If an error occurs in ldap_get_values() or ldap_get_values_len(),
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.
Примечание (Note)
These routines dynamically allocate memory which the caller must
free using the supplied routines.
