Sleeping in SKILL

Hi,

 

 I need a function that would do a sleep for X milliseconds or seconds. I need to wait for an asynchronous task to complete so I'm polling a flag regularly, but I don't want to take the whole CPU in a while loop. Any idea ?

 

 Thank you,

Guillaume

    SKILL is in fact single threaded, as you have noted. However, in practice, a background process communicating via ipcBeginProcess will cause the data handler to get invoked at the first opportunity that the virtuoso SKILL toplevel is available - i.e. when the UI returns.

    Functions such as ipcSleep and sleep will block virtuoso however.

    I'm not sure why the background process would get held up, unless it is producing so much output that the output buffer is being filled because the foreground SKILL process is not able to process it?

    It's very hard to tell without knowing the details of what you're doing...

    Regards,

    Andrew.
