How to execute skill commands in background ?

Amar Kumar

Hey There,

I want to excecute some skill commands in background which was my main purpose & display results to user.

For which i wrote,

ipcId = ipcBeginProcess("virtuoso -nograph -replay skillFile.il -log myLogFile.log")

"skillFile.il" file creates some file in my working directory.Its taking around 5mins.But i am not able to know when those file creation are completed.

I just want to execute some more skill commands in my current virtuoso only if those files are created.

 

So is there any command which will check in background the "ipcId" functions are executed or still under execution ?

I could have use ipcWait(ipcId) to wait ,but it hangs my current virtuoso or i can check after 5mins through "ipcIsAliveProcess(ipcId)".

But i dont want my current virtuoso to be hang or also dont want to check again or press another bindkey after 5 mins.

Please help me if there is any command which will check automatically after 5 mins in the background if icpId is alive or not.

 

Thanks In Advance,

Amar Kumar

  • You can't put a callback string as the argument to ipcBeginProcess. It has to be the name of a function (the documentation is fairly clear on this). If you had passed 'MyExitHandler it would have not worked because the status is an integer, not a string, so the printf would have failed. SKILL traps any errors in the exit handler, so maybe that's why you didn't notice it working.

    If you'd done:

    procedure(MyExitHandler(cid status)
      printf("MyIpcDone\n")
    )

    ipcBeginProcess("virtuoso -nograph -replay skillFile.il -log myLogFile.log" 'MyDisplayStuff 'MyDisplayStuff 'MyExitHandler)

    It probably would have been fine.
