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().ERRORSIf 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. NOTESThese routines dynamically allocate memory which the caller must free using the supplied routines.
