34 .Nd flush filesystem buffers for a file
39 .Fn VOP_FSYNC "struct vnode *vp" "int waitfor" "int flags"
41 This call flushes any dirty filesystem buffers for the file.
42 It is used to implement the
49 .Bl -tag -width waitfor
51 the vnode of the file.
53 whether the function should do data, meta-data updates or be full-synchronous.
55 are additional flags to be passed to the filesystem specific
62 can use the following flags:
63 .Bl -tag -width ".Dv MNT_NOWAIT"
65 is for an asynchronous data pass and a meta-data pass as well.
67 means a limited amount of data from dirty buffers and a full meta-data synchronization pass.
71 try to do a full synchronization pass.
72 That is, a meta-data pass and multiple data passes.
77 is to specify additional flags passed to the filesystem specific
80 The only supported flag at the moment is
82 which indicates the file synchronization was requested from userland.
84 Zero is returned if the call is successful, otherwise an appropriate
85 error code is returned.
89 The filesystem is full.
