These functions are used to retrieve
and manipulate attribute values from an LDAP entry as returned by ldap_first_entry(3LDAP) or ldap_next_entry(3LDAP). 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(3LDAP) or ldap_next_attribute(3LDAP), 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() function 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().
