Maybe we got to a wrong foot here. I will try to rephrase: I am familiar with C's preprocessor conditional inclusions. What I was not familiar with is in which cases do __CHECKER__ and __CHECK_ENDIAN__ get defined. I did find about the above later on. __CHECKER__ is defined when a tool, Sparse, is used to find possible coding faults from Linux kernel. [1] __CHECK_ENDIAN__ is used to mark the typedeffed types as restricted. [1] http://en.wikipedia.org/wiki/Sparse - Esa-Matti Mourujärvi / sukeri
