NAME
pseudofs —
pseudo file system construction kit
SYNOPSIS
#include
<fs/pseudofs/pseudofs.h>
DESCRIPTION
Thepseudofs 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.
SEE ALSO
linprocfs(5), linsysfs(5), procfs(5), sbuf(9), vnode(9)HISTORY
Thepseudofs module appeared in FreeBSD
5.0.
