@ Zac67 Wikipedia is where I got my first info. and thanks.
@ Moto
In my opinion a Library works similar to a function. I would like to know on a low level how an application that I write is able to Interface with the OS. I believe I understand what an API does but how does it? If an app. needs to access the disk and requests it through the Kernel how does it request it.
As far as which OS, Linux is one of the targets.
I believe there has to be a way for it to communicate.
Thanks.
