Thank you Manish; I think I am starting to approach an answer I hadn't thought of. Let me try it out below. Please correct me if I am wrong.

If anyone can confirm that there are other OS's that initiate prcesses differently from the Linux parent-child process. No details are really needed, I would just like to satisfy myself that either all OS's basically use the parent-child modal or that there are several different ways that it can be done. For example, would the Windows registry system be an alternative?? > Suppose if we had to start all the processes > from raw probably setting the initial values for the task just as > swapper will take some time, and you might want to use some kind of > template from you can derive the default values of the raw process > quickly.....isn't it ??? .......

By passing those constant values on through a parent-child modal to each new process those new processes don't have to re-initialize those constants. Is this true? And, might there be other reasons to use a parent-child modal? > Ohh and isn't it the same parent child relationship that we were > discussing, or in other words it is a raw process getting default > values from a closest template ? > As stated above, this sounds close to a BINGO. > [snip > > > -- > Thanks & Regards, > ******************************************** > Manish Katiyar ( http://mkatiyar.googlepages.com ) > 3rd Floor, Fair Winds Block > EGL Software Park > Off Intermediate Ring Road > Bangalore 560071, India > *********************************************** -- Regards Bill -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
