Overview

Data/hint flags/masks for EVFILT_USER and friends in Kqueue On input, the top two bits of fflags specifies how the lower twenty four bits should be applied to the stored value of fflags.

On output, the top two bits will always be set to Note::FFNOP and the remaining twenty four bits will contain the stored fflags value.
