But what's really going on under those layers of abstraction?..
Deep inside, there's no process. (it doesn't really exist, it's merely an interpretation... a layer of abstraction)
What's there actually, is the actuation of the hardware.
It serves well as a general purpose utility.
And many things that achieve a similar functionality, eventually (or inevitably...) took a similar routine.
Thanks for the info.
The term "syscall" itself is confusing in this context...
