I think the implication is that the cross-OS parts are coded, as it
happens, in the linux coding style, using linux functions, but then a
Windows layer maps these to Windows specific functions.

E.g. msleep(), mutex_trylock(), etc are implemented in the Windows
layer by mapping them to the Windows functions to do the same.
