<fs/pseudofs/pseudofs.h>
The
pseudofs module offers an abstract API for
pseudo-file systems such as
procfs(5) and
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
pseudofs) and callbacks that report file
attributes or write the actual file contents into sbufs.

The
pseudofs module appeared in
FreeBSD 5.0.
