Hi,

Simply put.

The sysinit macro expands to a static structure using the "section" attribute 
which means the data ends up in a separate section after linking. Then the 
data in the sysinit section is scanned, sorted and executed at boot time or 
when you load a module. Sysuninit works in a similar way.
