Hi Duane,On Jul 18, 2007, at 8:43 AM, Duane Murphy wrote: I wanted to make sure I understood how symbols interact in kext's. If I use a generally available library and another kext also uses that library, will those symbols interact with each other when the kext are loaded? That is it possible that my kext will accidentally link to the symbols in the other kext using a the same library?
Not sure what you mean by "interact", but I'll take a stab at answering the question I think you're asking.
The kernel is one big monolithic namespace. All symbols in KEXTs must be unique across the system as they are linked into that one namespace. If a KEXT defines a symbol that already exists, the KEXT will not load.
That's why we strongly recommend using reverse-DNS naming for KEXT symbols.
Is that what you meant?
