Hi all,
I have a quick question regarding this one sentence about WAIT in the SSEQ documentation. It states:
"Finally, if the sseq record
successfully waits for targetRecord to finish processing, it is still possible for other records to process as an indirect result
of LNKn, and the sseq record
cannot wait for this indirectly caused processing to finish unless the database developer has arranged for the indirectly caused processing to be traceable by EPICS."
Two questions I have.
- Suppose LNKn processes a record called "rec_1" through CA, "rec_1" is forward-linked to "rec_2", and "rec_2" is forward-linked to "rec_3". Does the statement about indirect processing apply in the case of "rec_1", "rec_2", and "rec_3" all being
synchronous records when WAITn is set to be "Wait".
- Using the same example, except with "rec_1", "rec_2", and "rec_3" all being asynchronous records (StreamDevice), would indirect processing apply to this case
when WAITn is set to be "Wait"? For instance, would SSEQ just wait for "rec_1"'s completion routine or "rec_3"'s completion routine?
Thank you very much,
Andy
