|
|
* routine) in the order that the user specified those jobs.
|

|
|
* There is a "job_matched" variable in struct jobqueue, which is used
|
|
* to make sure that the "doentry()" will only be called once for any
|
|
* given job in JSORDER processing. The "doentry()" routine can turn
|
|
* that off, if it does want to be called multiple times when the job
|
|
* is matched by multiple specifiers.
|
|
*
|
|
* The JSORDER processing will also call the "doentry()" routine once
|
|
* after each scan of the queue, with the jobqueue set to null. This
|
|
* provides a way for the caller to print out a summary message for
|
|
* each jobspec that was given.
