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
<des@FreeBSD.org>.
