your construct:



[  1 ] (
    [  1 ] (
            [  143 ]             66 69 6c 73  -- fils
            )
        )
    )

shows the put param, and the first put cons. But the second put cons
seems to have entered garbage, event  the (())) dont line up correctly.

I would check the contents of your p_context to see what is in there.

Sorry, this is a mistake using cut and paste...

Here is my ilv_dump


[  1 ] (
    [  1 ] (
        [  1 ] (
            [  143 ]             66 69 6c 73  -- fils
            )
        )
    )

alright, with the new ILV things do look better. This brings us to the
statement:



	status = mcc_ilv_put (&put_ctx, attr_desc, 0);

This is where the 143 is coming from. You w will have to check out
the argument values you are using here.

status = mcc_desframe_create_descriptor(
          &(*p_context)->alloc_mem_list,    /*  Memory Allocation List  */
          &attr_desc,                      /*  Descriptor Pointer      */
          &1024,
          0,
          0,
          &1,
          &DSC_K_DTYPE_Z);

[  1 ] (
    [  1 ] (
        [  1 ] (
            [  143 ]             66 69 6c 73  -- fils
            )
        )
    )

I thought this &1 (the 6th argument) was the code which should appear instead
of this 143, I don't understand. 
My put_ctx already worked with another argument... 
I think that datatype and value fields are filled by the mcc_aes_get routine. 
When I check the type of my attr_desc I get code 3 which is MCC_K_DT_LATIN1STRING
And 'fils' is the instance I'm desesperatly trying to get...

This 143 is a mystery for me.

I think that I got this problem when I use Latin1String, because, I've done the
same thing with Integer32 and it works!

I'm wondering if mcc_desframe_create_descriptor works the way I think it works:

Is really the id code (the 6th argument) the one which should correspond to
the code of the event parameter in the MSL?

thanks

Francois

Hi Francois,

I just check the code for the Design Framework, and you have the
arguments positioned correctly; that is:

mcc_desframe_create_descriptor(
  **memory_list,
  **descriptor,
   *length,
   *mcc_datatype,
   *value,
   *id,
   *vms_datatype );

The descriptor created for you should contain:

  o  a buffer of 1024 bytes
  o  a '0' for the MCC datatype
  o  no initial value
  o  a '1' for the Id
  o  'dtype_z' value for the vms datatype

I'm sure if you exam the descriptor after calling create_descriptor
this is what you'll see.

After the call to 'mcc_aes_get' the descriptor will contain the values
from the Entity Specification.  The fields updated by aes_get are:

  o  mcc_w_curlen
  o  mcc_l_id
  o  mcc_l_dt
  o  mcc_a_pointer (that is,the buffer pointed to by this field)

The only thing I can think of is the 'id' field in the Entity
Specifiation is '143'

In-Entity is built by the FCL from information from the 
Dictionary ... what is the Identifier Attribute code for the Entity?

Remember too, the 'mcc_aes_get' level argument begins at 0.  0 is the
global entity class, 1 is the first child entity class, ...

Unless you only need/want a latin1string in your event, you can use
the full entity (ie, in-entity) as an event argument (so long as you
define this in the MSL)

Also, in 1073.0 - you show some coding examples .. but are you checking
the status from each call?  Could you have got an error from aes_get?

Hope this helps,

Thanks Keith for the explanation.

You're right for the '143': Here is my Specification:
       

	IDENTIFIER ATTRIBUTES
             ATTRIBUTE toID = 143 : Latin1String
                ACCESS = NONSETABLE,
                DISPLAY = TRUE,
                SYMBOL = ATTR_TOID,
                DEFAULT = "0",
                CATEGORIES = ( CONFIGURATION )
             END ATTRIBUTE toID;

             ATTRIBUTE objectClass = 101 : Latin1String
                ACCESS = NONSETABLE,
                DISPLAY = TRUE,
                SYMBOL = ATTR_OBJECTCLASS,
                CATEGORIES = ( CONFIGURATION )
             END ATTRIBUTE objectClass;

       END ATTRIBUTES; (* IDENTIFIER *)

I only need a Latin1String for my event argument.

There a status checking after each call in my code, so I know there is no error
from the aes_get.

From your explanation I guess what I need to do is to force the mcc_l_id
to the value I want (the code of my event parameter) ""after"" the call to 
the aes_get? That way, the mcc_l_id of the descriptor and the code of my 
parameter will match...

Am I right, or is there something I'm missing?

Francois

change the ild, and make sure the dt is correct, and the a_link is null.

I was trying this, and it works fine...

Thanks Jill and Keith

Francois.

status = mcc_desframe_create_descriptor(
          &(*p_context)->alloc_mem_list, 
          &desc_NUMBER_1,                     
          &1024,
          0,
          0,
          0,
          0);

status = mcc_aes_get (&p_callargs->p_in_entity, &1,
                             &class_code, desc_NUMBER_1, MCC_K_NULL_PTR);

status = mcc_desframe_create_descriptor(
          &(*p_context)->alloc_mem_list, 
          &desc_NUMBER_2,                     
          0,
          &MCC_K_DT_LATIN1STRING,
          desc_NUMBER_1->mcc_a_pointer,
          &MCC_K_ARG_MY_PARAMETER_CODE
          &DSC_K_DTYPE_Z );

status = mcc_ilv_put (&put_ctx, desc_NUMBER_2, 0);

Is it the right (clean) way of doing what I wanna do?

Francois

I would :

	o Create the Descriptor
	o Call mcc_aes_get
	o Set the mcc_l_id field of the Descriptor
	o (May have to set datatype if it isn't what you want from the aes_get)
	o Call mcc_ilv_put

No need to create a new descriptor

------------------------------------

status = mcc_desframe_create_descriptor(
          &(*p_context)->alloc_mem_list, 
          &desc_NUMBER_1,

                             &class_code, desc_NUMBER_1, MCC_K_NULL_PTR);

desc_NUMBER_1->mcc_l_id = MCC_K_ARG_MY_PARAMETER_CODE;
desc_NUMBER_1->mcc_l_dt = MCC_K_DT_LATIN1STRING;

status = mcc_ilv_put (&put_ctx, desc_NUMBER_1, 0);

Thanks, I'll do it the way you suggest.

Francois.
