     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
          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 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
          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_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.
