31.Sh NAME
32.Nm pseudofs
33.Nd pseudo file system construction kit
34.Sh SYNOPSIS
35.In fs/pseudofs/pseudofs.h
36.\" Insert usage example here
37.Sh DESCRIPTION
38The
39.Nm
40module offers an abstract API for pseudo-file systems such as
41.Xr procfs 5
42and
43.Xr linprocfs 5 .
44It takes care of all the hairy bits like interfacing with the VFS
45system, enforcing access control, keeping track of file numbers, and
46cloning files and directories that are process-specific.
47The consumer module, i.e., the module that implements the actual guts
48of the file system, needs only provide the directory structure
49(represented by a collection of structures declared and initialized by
50macros provided by
51.Nm )
52and callbacks that report file attributes or write the actual file
53contents into sbufs.
