pseudofs - pseudo file system construction kit
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.
linprocfs(5), linsysfs(5), procfs(5), sbuf(9), vnode(9)
The pseudofs module appeared in FreeBSD 5.0.
