Indeed, surely Mac OS includes its own man pages? man 2 mprotect, man 2 unlink

[saagarjha]

It does, but they generally match those in Linux pretty closely due to POSIX.

on the higher level yes, but anything dealing with lower level things like kernel interfaces, devices, etc no

(similar situation for other unices and posix-likes)

[saagarjha]

Yes, but mprotect and unlink are both high level API calls.
