1096.0. "MCC_S_INV_ENTITY in mcc_dict_build_spec" by PHONE::ALLAIN () Wed Jun 05 1991 10:35

Hi everybody,

I'm getting an MCC_S_INV_ENTITY and I don't know how to fix it:

The call to mcc_dict_build_spec returns me a MCC_S_INV_ENTITY status. 

Does someone have any idea about this?

I enclosed the piece of code at the end of the note. I'm trying to get the name
of the class from its code, and to use the mcc_dict_translate_name_code seems to 
be the way of doing this... But for that, I need to build a dict_spec...

Thanks

Francois


PS: The p_callargs->p_in_entity must be good because I can use it for getting 
the name of the instance of my entity, so I think the probleme is around this
dict_spec...

MCC_T_Descriptor                *temp_desc = MCC_K_NULL_PTR;


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

                                &DSC_K_DTYPE_L);

printf("\n St = %d", status);

temp_desc->mcc_a_pointer = &class_code;
status = mcc_dict_build_spec (  p_callargs->p_in_entity,
                                                &dict_spec,
                                                0,

1096.1	For what it's worth...	TOOK::GUERTIN	I do this for a living -- really	`Wed Jun 05 1991 12:08`	6
	Although I can't see anything wrong with the entity specs, the arguments look a little funny to me. How can you have a NULL class with an instance? Did you try specifying a dictionary class? (Or passing in a NULL for the instance as well.) -Matt.
1096.2	MCC_S_NOENTITY now...	PHONE::ALLAIN		`Wed Jun 05 1991 13:10`	44
	OK, I thought I tried it, but obviously not, because it works now! Thank you. I have a problem now for the next call.... If you had an idea, that would be great... Here is my code (updated with MCC_K_DICT_CLASS...): status = mcc_desframe_create_descriptor( &(p_context)->alloc_mem_list, &temp_desc, &sizeof (MCC_T_Integer32), &MCC_K_DT_INTEGER32, &class_code, 0, &DSC_K_DTYPE_L); status = mcc_dict_build_spec ( p_callargs->p_in_entity, &dict_spec, &MCC_K_DICT_CLASS, temp_desc); status = mcc_desframe_create_descriptor( &(p_context)->alloc_mem_list, &ev_src_obj_class_desc, &100, &MCC_K_DT_INTEGER32, &class_code, 0, 0); status = mcc_dict_translate_name_code ( dict_spec, ev_src_obj_class_desc, 0); And the call to mcc_dict_translate_name_code returns me a MCC_S_NOENTITY status. Any idea about this? Thanks in advance Francois
1096.3	what are you doing?	TOOK::CALLANDER	Jill Callander DTN 226-5316	`Wed Jun 05 1991 13:14`	20
	if you have a valid in_e and what to create a dict spec, simply call the build_dict_spec with the in_e. That will convert: in_e dict_spec class: your entity class class: mcc_k_dict_class instanse: your instance instance: your entity class MCC_A_AES dict_spec = MCC_K_NULL_PTR; status = mcc_dict_build_spec ( p_callargs->p_in_entity, >>>> see * &dict_spec, MCC_K_NULL_PTR, MCC_K_NULL_PTR); ** I am not sure how p_callargs->p_in_entity is defined but the dict_build_spec says that the first argument is an MCC_A_AES passed by value, not by reference. Please check to see if an "*" is needed here.
1096.4	what are you doing?	TOOK::CALLANDER	Jill Callander DTN 226-5316	`Wed Jun 05 1991 13:14`	20
1096.5	call mcc_aes_dumpt	TOOK::CALLANDER	Jill Callander DTN 226-5316	`Wed Jun 05 1991 13:17`	3
	put in a debug call to mcc_aes_dump (I think it is in the vector file so you should be able to get at it), and see what the contents of the dict spec look like.
1096.6	Waouh!!!	PHONE::ALLAIN		`Wed Jun 05 1991 13:32`	25
	This is the dump of my dict_spect entity [0] wild = NOT_WILD class = 1 id = 0 type = 35 instance = �... %XE9030000 entity [1] wild = NOT_WILD class = 2 id = 0 type = 35 instance = �... %XF9030000 entity [2] wild = NOT_WILD class = 1 id = 0 type = 31 instance = �... %XF9030000 This the way I call the dump: status = mcc_aes_dump (dict_spec); printf("\n St 12.8 = %d", status); This the status I get from the dump..., but i couldn't find it in the library! St 12.8 = 704524 Does that look good?
1096.7	mcc_aes_dump is declared void	TOOK::KOHLS	Ruth Kohls	`Wed Jun 05 1991 13:50`	12
	>This the way I call the dump: > > status = mcc_aes_dump (dict_spec); > printf("\n St 12.8 = %d", status); > don't bother with the status of mcc_aes_dump. Its declared void. The dump looks similar to other aes dumps. I didn't look to see if I could tell if it was what you wanted, though. Ruth
1096.8	Ok	PHONE::ALLAIN		`Wed Jun 05 1991 15:05`	11
	Ok, i removed (set it to MCC_K_NULL_PTR...) the last 2 parameters of my build_spec call, and everything is solved... You were right Jill. Thanks a lot. The only thing is that I tried to append something at the end of the dict_spec because I missunderstood the SRM for the mcc_dict_translate_name_code routine... Sorry about this. Thanks to everybody. Francois
1096.9	call is fine, spec is bad	TOOK::CALLANDER	Jill Callander DTN 226-5316	`Wed Jun 05 1991 15:08`	31
	entity [0] wild = NOT_WILD class = 1 id = 0 type = 35 instance = �... %XE9030000 entity [1] wild = NOT_WILD class = 2 id = 0 type = 35 instance = �... %XF9030000 entity [2] wild = NOT_WILD class = 1 id = 0 type = 31 instance = �... %XF9030000 the types (mcc_k_dt) are in mcc_interface_def.h as well as the classes (mcc_k_dict). type 35 = unsigned32 type 31 = interger32 (not the same thing) class 1 = mcc_k_dict_class (for use in GLOBALS only!!, see your third level) class 2 = mcc_k_dict_subclass Now note that you have id=0 all the way down, that is right, but the instance should have the codes associated with the request. Like the first one, is your class code really %XE903? or is that the name? Note that translate name requires you use a dt of latin1string or unsiged32 on the last instance to determine what to translate from/to. BTW: I have only ever used the translate to translate the last item on the AES, it looks like you are trying to do the whole thing, I will ask Matt if that is possible (SRM implies it is).
