pseudofs — pseudo
file system construction kit
#include
<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.
The pseudofs module and this manual page
were written by Dag-Erling Smørgrav
