Res: [ts-7000] Re: CPU spikes on 7350 for tsscarda

If volatility of data is not an issue as pointed out below...

 

You could also create either one of the IPC resources that are OS native. They are all relativelly simple to use:

 

    * pipe between the threads or processes.

Or  * messages.

 

Or  * Shared memory.

 

I would recommend first 2 because itÂs implied sequence and delivery, 3rd option if you want to have fun with semaphores and/or other kind of control to avoid races between the provider and the consumer of your data.

 

If you use sockets you should be able, in som efuture, to port your application to a remotely distributed application since the code will be already implemented in sockets.

Just out of curiosity, why don't you use a RAM filesystem and read/write files there? Is it essential that the data survives a reboot?
