/*
|
|
* FUSE uses a number of types (notably: struct stat) that are OS specific.
|
|
* Furthermore there are sometimes multiple definitions of the same type even
|
|
* within the same OS. This is certainly true on Windows, where these types
|
|
* are not even native.
|
|
*
|
|
* For this reason we will define our own fuse_* types which represent the
|
|
* types as the WinFsp DLL expects to see them. When the file is included
|
|
* by FUSE clients in different environments we will translate between their
|
|
* understanding of the types and ours.
