Is it possible to return the FLUID job id from flux-submit as decimal?

[dblitt]

I am currently working on an integration for Flux into cctools/batch_queue so we can easily submit generic jobs into a Flux instance from this shared API. The current plan is basically to call popen("flux submit ...") (so as to be as portable as possible) and parse the output to obtain the jobid, however it seems that flux-submit always returns the jobid in F58 format (possibly in unicode), and I would rather not have to parse this if not necessary, because our internal format keeps the jobid as a decimal.

You could popen the following command line:

$ flux submit -n4 hostname | flux job id --to=dec
353630158848

Note that the integer returned here is 64 bit unsigned where it looks like cctools uses int64_t from a peek at that link. Just something to keep in mind.

Alternately, the Flux API does export flux_job_id_parse(3) which can parse a jobid in any format into flux_jobid_t (which is a typedef of uint64_t).
