Hi all,
It looks like the cygrunsrv utility hardcodes 30 seconds as a maximal time for a service to start, then bails
out with a failure.
It would be quite useful (in certain situations) to have a command-line parameter (for the -I option)
that can specify a service startup timeout, longer or shorter than the preset default.
Thanks for considering this,
Anton Lavrentiev
P.S. Maybe for the service shutdown as well, separate or the same parameter used.

Patches welcome! The source is at

No, 30 seconds is a hard system timeout in which a service must reply with an
appropriate control message to let services.exe know it is ready to continue
startup sequence.

Is there such a feature at all to begin with?
A link to MSDN would suffice.

Oh, really? If so, I completely forgot about that...

This is the best I could dig right now at the subject.
https://www.codeproject.com/Articles/499465/Simple-Windows-Service-in-Cplusplus
And MSDN article https://docs.microsoft.com/en-us/windows/desktop/services/the-complete-service-sample
Looks much the same.
All the internet flooded with useless "pick 'service application' template in
Visual Studio" crap, hiding the actually useful information.
May be some more time spent in Google with control signal names reveal even
older (== more useful) articles.
Don't have that time right now, sorry. :(

I don't think there is a hard-coded system timeout, as long as the starting service keeps
posting its START_PENDING status, the service controller will wait.
And cygrunsrv seems to be doing that already.
MSDN doc says exactly that. And I've also seen some articles that tell the same.
