.Fd #include <fs/pseudofs/pseudofs.h>

|
.Sh DESCRIPTION
|
|||
|
|
The
|
|||
|
|
.Nm
|
|||
|
|
module offers an abstract API for pseudo-filesystems such as
|
|||
|
|
.Xr procfs 5
|
|||
|
|
and
|
|||
|
|
.Xr linprocfs 5 .
|
|||
|
|
It takes care of all the hairy bits like interfacing with the VFS
|
|||
|
|
system, 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 filesystem, need 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.
