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
              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 calendar 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.
