.Dd April 20, 2007 .Dt PSEUDOFS 9 .Os .Sh NAME .Nm pseudofs .Nd pseudo file system construction kit .Sh SYNOPSIS n fs/pseudofs/pseudofs.h Insert usage example here
.Sh DESCRIPTION The .Nm module offers an abstract API for pseudo-file systems such as .Xr procfs 5 and .Xr linprocfs 5 . It takes care of all the hairy bits like interfacing with the VFS system, enforcing access control, keeping track of file numbers, and cloning files and directories that are process-specific. The consumer module, i.e., the module that implements the actual guts of the file system, needs only provide the directory structure (represented by a collection of structures declared and initialized by macros provided by .Nm ) and callbacks that report file attributes or write the actual file contents into sbufs. Insert more info here
.Sh SEE ALSO .Xr linprocfs 5 , .Xr linsysfs 5 , .Xr procfs 5 , .Xr sbuf 9 , .Xr vnode 9 .Sh HISTORY The .Nm module appeared in .Fx 5.0 . .Sh AUTHORS The .Nm module and this manual page were written by .An Dag-Erling Sm\(/orgrav Aq des@FreeBSD.org .
