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

SYNOPSIS
       #include <xcsa.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 num‐
       ber_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	infor‐
       mation from the function.  A value of NULL indicates that the caller is
       not using any extensions.  See the extensions structure for more infor‐
       mation.

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 allocated 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 available in the  extension.
       See  the	 extensions structure for more information.  Whether the func‐
       tion 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 following error val‐
       ues:

       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 spec‐

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		 The specified Session Handle is invalid or  no	 longer	 valid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

       CSA_E_SERVICE_UNAVAILABLE
		 The requested calendar service is unavailable.

       CSA_E_UNSUPPORTED_ATTRIBUTE
		 An  attribute was encountered that is unsupported by the cal‐
		 endar service.

       CSA_E_UNSUPPORTED_FLAG
		 The flag requested is not supported.

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