FUSE - detailed documentation

view story

http://stackoverflow.com – trying to get my own filesystem working using fuse (filesystem in user space, linux) im really curious on where to get detailed up to date documentation of the operations used? most time i search for other file system implementations and see what they do, but some operations seem to be not widely used like poll/ioctl or bmap. and the documentation of the fuse api doesnt help much, cause e.g. the parameters and return values of the operations are not documented thus i have to guess how to use em so the question is where do i get better information about how such exotic operations are supposed (HowTos)
