NAME
     csa_update_calendar_attributes - update the calendar  attri-
     butes values for a calendar

SYNOPSIS
     #include <csa.h>
     CSA_return_code csa_update_calendar_attributes(CSA_session_handle session,
                                                    CSA_uint32 number_attributes,
                                                    CSA_attribute *calendar_attributes,
                                                    CSA_extension *update_calendar_attributes_extensions);

DESCRIPTION
     The  csa_update_calendar_attributes()  function  update  the
     values of the calendar attributes of the specified calendar.
     The existing value  of  each  specified  attribute  will  be
     replaced  by the new value specified in calendar_attributes.
     New attributes can be added using this function and existing
     attributes  can  be effectively deleted by setting the value
     part of the CSA_attributes structure to NULL.   If  a  read-
     only  attribute  is  specified, the error CSA_E_READ_ONLY is
     returned by the function.  If the function returns an error,
     none  of the specified attributes will be updated.  Only the
     owner of the calendar, users  with  CSA_OWNER_RIGHTS,  users
     with  CSA_INSERT_CALENDAR_ATTRIBUTES access rights, or users
     with CSA_UPDATE_CALENDAR_ATTRIBUTES, can update the calendar
     attributes.

ARGUMENTS
  Session (Session Handle)
     Opaque session handle that represents  a  session  with  the
     calendaring service.

     Session handles are created by a  logon  function  call  and
     invalidated  with  a  logoff  function call.  If the session
     handle      is      invalid,      then       the       error
     CSA_E_INVALID_SESSION_HANDLE is returned.

  Number Attributes (Uint32)
     The number of calendar attributes in calendar_attributes.

  Calendar Attributes (Attribute)
     A pointer to an array of attribute structures containing the
     new values for the calendar attributes.

  Update Calendar Attributes Extensions (Extension)
     A pointer to an array of CSA_extension structures  for  this
     function.   The  array may contain both input extensions for
     providing additional information to the function and  output
     extensions  for  receiving information from the function.  A
     value of NULL indicates that the caller  is  not  using  any
     extensions.    See   the   extensions   structure  for  more

     information.

RETURN VALUE
  Update Calendar Attributes Extensions (Extension)
     If output extensions were passed  to  the  function  in  the
     extensions list, the results from the service will be avail-
     able in the extension.  See  the  extensions  structure  for
     more  information.   Whether  the function succeeded or not,
     and, if not, why.  It may be success or one  of  the  values
     listed under ERRORS below.

     following error values:

              The data extension requested is invalid.

        CSA_E_INVALID_FLAG
              A flag value in the flags argument was invalid.

        CSA_E_INVALID_FUNCTION_EXT
              The function extension requested is invalid.

        CSA_E_INVALID_PARAMETER
              A function parameter was invalid.

        CSA_E_INVALID_SESSION_HANDLE

              The specified  Session  Handle  is  invalid  or  no
              longer valid (e.g., after logging off).

        CSA_E_NO_AUTHORITY
