csa_call_callbacks(3)  C LIBRARY FUNCTIONS  csa_call_callbacks(3)

NAME
     csa_call_callbacks	- force	the invocation	of  the	 callback
     functions associated with the specified callback list(s)

SYNOPSIS
     #include <csa.h>

     CSA_return_code csa_call_callbacks(CSA_session_handle session,
					CSA_flags reason,
					CSA_extension *call_callbacks_extensions);

DESCRIPTION
     The csa_call_callbacks() function causes the service to call
     the  registered  callback	functions  associationed with the
     specified callback	list(s).  The service will  process  each
     specified	callback  list	and  call the registered callback
     functions if there	have been changes that would trigger  the
     callbacks	of  that  type.	 The order in which callbacks are
     invoked is	implementation specific.

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

     If	a valid	session	handle is specified, the  callback  func-
     tions  registered	with  that  session are	invoked.  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.

  Reason (Flags)
     A bitmask of flags.   Unspecified	flags  should  always  be
     passed  as	 0.   Undocumented flags are reserved.	Each flag
     corresponds to a callback activity.  Flag settings	include:

	CSA_CB_CALENDAR_LOGON
	      If set, the new callback will be invoked when a the
	      calendar is accessed by a	user.

	CSA_CB_CALENDAR_DELETED
	      If set, the new callback will  be	 invoked  when	a
	      user requests that the calendar be deleted.

	CSA_CB_CALENDAR_ATTRIBUTE_UPDATED
	      If set, the new callback will be invoked whenever	a
	      calendar attribute is updated.

	CSA_CB_ENTRY_ADDED
	      If set, the new callback will be	invoked	 whenever
	      an entry is added	to the calendar.

	CSA_CB_ENTRY_DELETED

	      If set, the new callback will be	invoked	 whenever
	      an entry is deleted from the calendar.

	CSA_CB_ENTRY_UPDATED
	      If set, the new callback will be	invoked	 whenever
	      an  entry	is updated on the calendar.  It	is imple-
	      mentation	specific  if  the  callback  function  is
	      invoked  before  or after	the specified update type
	      occurs.

  Call Callbacks 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 informa-
     tion.

RETURN VALUE
  Call Callbacks 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.

ERRORS
     The  csa_call_callbacks()	function  returns  the	following
     error values:

	CSA_E_FAILURE
	      There was	a general failure that does not	 fit  the
	      description of any other error code.

	CSA_E_INSUFFICIENT_MEMORY
	      Insufficient memory was available	to  complete  the
	      requested	operation.

	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).
