.Sh DESCRIPTION
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
2002-12-12 17:26:04 +00:00
|
|
|
module offers an abstract API for pseudo-file systems such as
|
2001-09-30 18:07:55 +00:00
|
|
|
.Xr procfs 5
|
|
|
|
|
and
|
|
|
|
|
.Xr linprocfs 5 .
|
|
|
|
|
It takes care of all the hairy bits like interfacing with the VFS
|
2001-12-04 14:28:38 +00:00
|
|
|
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
|
2002-12-12 17:26:04 +00:00
|
|
|
of the file system, needs only provide the directory structure
|
2001-09-30 18:07:55 +00:00
|
|
|
(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.
