NAME
   sec_key_mgmt_get_next_kvno - Retrieves the next eligible key version
                                number for a key

 SYNOPSIS

 #include <dce/keymgmt.h>

 void sec_key_mgmt_get_next_kvno(
         sec_key_mgmt_authn_service authn_service,
         void *arg,
         idl_char *principal_name,
         void *keytype,
         unsigned32 *key_vno,
         unsigned32 *next_key_vno,
         error_status_t *status);

 PARAMETERS

 Input

 authn_service
        Identifies the authentication protocol using this key.  The
        possible authentication protocols are as follows:

        rpc_c_authn_dce_secret
                    DCE shared-secret key authentication.

        rpc_c_authn_dce_public
                    DCE public key authentication (reserved for future
                    use).

 arg    This parameter can specify either the local key file or an
        argument to the get_key_fn key acquisition routine of the
        rpc_server_register_auth_info routine.  A value of NULL specifies
        that the default key file (DCE$LOCAL:[KRB]V5SRVTAB.;) should be
        used.  A key file name specifies that file should be used as the
        key file.  You must prepend the file's absolute filename with
        FILE: and the file must have been created with the rgy_edit ktadd
        command or the sec_key_mgmt_set_key routine.  Any other value
        specifies an argument for the get_key_fn key acquisition routine.
        See the rpc_server_register_auth_info() reference page for more
        information.

 principal_name
        A pointer to a character string indicating the name of the
        principal associated with the key.

 keytype
        A pointer to a value of type sec_passwd_type_t.  The value
        identifies the data encryption algorithm (for example, DES)
        being used for the key.

 Output

 key_vno
        The current version number of the key.  Specify NULL if you do
        not need this value to be returned.

 next_key_vno
        The next eligible version number for the key.  Specify NULL if
        you do not need this value to be returned.

 status
        A pointer to the completion status.  On successful completion,
        the routine returns error_status_ok.  Otherwise, it returns an
        error.

 DESCRIPTION

 The sec_key_mgmt_get_next_kvno() routine returns the current and next
 eligible version numbers for a key from the registry server (not from
 the local key table).  The key is identified via its associated
 authentication protocol, principal name, and key type.  The arg value
 associated with the key is also specified.

 FILES
       SYS$COMMON:[DCE$LIBRARY]KEYMGMT.IDL
              The idl file from which dce/keymgmt.h was derived.

 ERRORS

 sec_key_mgmt_e_key_unavailable
              The requested key is not present.

 sec_key_mgmt_e_authn_invalid
              The authentication protocol is not valid.

 sec_key_mgmt_e_unauthorized
              The caller is not authorized to perform the operation.

 sec_rgy_server_unavailable
              The DCE Registry Server is unavailable.

 sec_rgy_object_not_found
              No principal was found with the given name.

 error_status_ok
              The call was successful.
