33 .Nd check if vnode is exported to a client
38 .Fn VFS_CHECKEXP "struct mount *mp" "struct mbuf *nam" "int *exflagsp" "struct ucred **credanonp"
40 This is used by the NFS server to check if a mount point is exported
44 .Bl -tag -width credanonp
46 The mount point to be checked.
48 An mbuf containing the network address of the client.
50 Return parameter for the export flags for this client.
52 Return parameter for the anonymous credentials for this client.
55 This should be called on a file system's mount structure to determine if it
56 is exported to a client whose address is contained in
59 It is generally called before
61 to validate that a client has access to the filesystem.
63 The filesystem should call
64 .Xr vfs_export_lookup 9
65 with the address of an appropriate
67 structure and the address of the client,
69 to verify that the client can access this filesystem.
71 The export flags and anonymous credentials specific to the client (returned
73 .Xr vfs_export_lookup 9 )
