NAME
     csa_read_calendar_attributes - read and return the  calendar
     attributes values for a calendar

SYNOPSIS
     #include <csa.h>
     CSA_return_code csa_read_calendar_attributes(CSA_session_handle session,
                                                  CSA_uint32 number_names,
                                                  CSA_attribute_reference *attribute_names,
                                                  CSA_uint32 *number_attributes,
                                                  CSA_attribute **calendar_attributes
                                                  CSA_extension *read_calendar_attributes_extensions);

DESCRIPTION
     The csa_read_calendar_attributes() function returns an array
     of attributes structures containing the values of the calen-
     dar attributes of the specified calendar.  The function will
     return  all  of  the  attributes if number_names argument is
     zero and attribute_names argument is NULL.  Only  the  owner
     of  the calendar, users with CSA_OWNER_RIGHTS, or users with
     CSA_VIEW_CALENDAR_ATTRIBUTES  access  rights  can  read  the
     calendar atttributes.

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 Names (Uint32)
     The number of calendar attribute names  in  attribute_names.
     If  zero,  then  all of the attributes will be returned.  If
     the attribute_names argument is  NULL,  then  this  must  be
     zero.

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

  Read 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 informa-
     tion.

RETURN VALUE
  Number Attributes (Uint32)
     A  pointer  to  the  number  of   attributes   returned   in
     calendar_attributes.  The error CSA_E_INSUFFICIENT_MEMORY is
     returned if there is the service has insufficient memory  to
     store the complete set of requested information.

  Calendar Attributes (Attribute)
     A pointer to an array of attribute structures containing the
     values  for the calendar attributes for the specified calen-
     dar.  This array is allocated by the service, and should  be
     freed with a single call to csa_free(3).

  Read 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.

ERRORS

     lowing 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

              attribute.

        CSA-E_INVALID_FLAG

        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
              The user has insufficient authority for this  func-
              tion.

        CSA_E_NOT_SUPPORTED
              The operation requested is not  supported  by  this
              implementation.

        CSA_E_SERVICE_UNAVAILABLE
              The requested calendar service is unavailable.

        CSA_E_UNSUPPORTED_ATTRIBUTE
              An attribute was encountered that is unsupported by

        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.
