3136.0. "Some minor questions" by CCIIS1::ROGGEBAND () Fri Jun 05 1992 12:54

Hi,

I have a set of unrelated minor questions :

Context : DECmcc T1.2.4 (upgrade to T1.2.7 planned for next week) on VMS

1) When using the MCC Datatype HexString, which base type should be used ?
   The SRM specifies DSC_K_DTYPE_HHBS but that type doesn't seem to be
   defined, so I used DSC_K_DTYPE_T instead. Is this correct ?

2) Registration FM and wildcard support : the DEREGISTER command supports
   wildcard for global entities, but not for child entities. This seems a
   bit weird ?

3) When calling the mcc_thread_get_attribute service, the following message
   is displayed :

   *** TBS: mcc_thread_get_attribute

   I presume this is a trace message which was not edited out of the source
   code ?

Thanks, amicalement,

Philippe.

Is this correct ? Use DSC_K_DTYPE_HHBS for Hexstring. This constant is defined in mcc_descrip.h. However, right now this field is not crucial. What is important is that the mcc_w_curlen field of any descriptor of a hexstring contains the length of the hexstring in NIBBLES, (or half-bytes). This enables ILV and other protocols to handle the case of a hex string with an odd length. Ruth K.
3136.2	thread_get_attribute isn't implemented	DADA::DITMARS	Pete	`Fri Jun 05 1992 14:18`	11
	TBS stands for one of the following: To Be Specified - as in, under DECthreads, what does a "thread attribute" mean? To Be SeparatedFromTheDocumentation - as in I doubt this routine is going to be supported in the future I recommend that you find another way to convey whatever information you hoped to obtain from the thread_get_attribute routine.

	Sorry, but the mcc_thread_get_attribute rtn did not get re-implemented during the change from v1.1 to v1.2 which uses DECthreads. TBS - "to be specificied" at a later date. I recommend that you use the DECthreads rtns for retrieving attributes about thread objects. \Pete
