NAME
     csa_read_entry_attributes - read  and  return  the	 calendar
     entry attribute values for	a specified calendar entry

SYNOPSIS
     #include <csa.h>

     CSA_return_code csa_read_entry_attributes(CSA_session_handle session,
					       CSA_entry_handle	entry,
					       CSA_uint32 number_names,
					       CSA_attribute_reference *attribute_names,
					       CSA_uint32 *number_attributes,
					       CSA_attribute **entry_attributes,
					       CSA_extension *read_entry_attributes_extensions);

DESCRIPTION
     The csa_read_entry_attributes() function returns an array of
     attribute structures containing the values	of the attributes
     of	the specified calendar entry.  The function  will  return
     all  of  the attributes if	number_names argument is zero and
     attribute_names argument is NULL.

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.

  Entry	(Entry Handle)
     The handle	of the calendar	entry to be read.  If  the  entry
     handle is invalid,	then the error CSA_E_INVALID_ENTRY_HANDLE
     is	returned.

  Number Names (Uint32)
     The number	of names in attribute_names.  If  attribute_names
     argument is NULL, then this must be zero.

  Attribute Names (Attribute Reference)
     A pointer to an array of attribute	names that reference  the
     attributes	that are to be read.  If number_names argument is
     zero, then	this must be NULL.

  Read EntryAttribute 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
  Number Attributes (Uint32)
     The number	of attributes returned in  entry_attributes.   If
     none  of  the  specified  attributes have values, a value of
     zero is returned.

  Entry	Attributes (Attribute)
     A pointer to an array of attributes.  This	pointer	is  allo-
     cated  by the service and should be freed with a single call
     to	csa_free(3).

  Read Entry Attribute 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_read_entry_attributes() function returns the follow-
     ing 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_ATTRIBUTE
	      An attribute was specified that was not defined  by
	      this  specification and the implementation does not
	      support the attribute as	an  application	 specific
	      attribute.

	CSA_E_INVALID_ENTRY_HANDLE
	      An invalid calendar entry	handle was specified.

	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

	CSA_E_UNSUPPORTED_FUNCTION_EXT
	      The specified function extension is  not	supported
	      or CSA_EXT_REQUIRED is set.
