 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() .  ERRORS
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.
 NOTES
These routines dynamically allocate memory which the caller must free
using the supplied routines.
