1. Introduction
---------------
This package's purpose is to provide a set of utilities for interfacing
with sysfs, a virtual filesystem in Linux kernel versions 2.5+ that
provides a tree of system devices. While a filesystem is a very useful
interface, we've decided to provide a stable programming interface
that will hopefully make it easier for applications to query system devices
and their attributes.
This package currently includes:
- libsysfs: a library for accessing system devices.
- systool: an application to view system device information by bus, class,
and topology.
- A number of example usage routines in the "test" directory.
- A comprehensive testsuite, also shipped as part of the "test" directory. This
testsuite can be used to test _all_ the APIs exported by Libsysfs.
Please refer the libsysfs.txt file in the "docs" directory for
details as to how to use the testsuite.
2. How to Install
-----------------
Run the "configure" script to generate Makefiles. Use "make" to build the
library and utilities.
For a successful install, run "make install" as super-user. "make uninstall"
will clean up all installed files.
2.1 Caveats/Known issues
------------------------
The header files (libsysfs.h and dlist.h) are installed in /usr/include/sysfs
by default. This _cannot_ be changed by using the --prefix or --includedir
parameters while running the "configure" script.
As a consequence, when a non-root user runs the "configure" script with these
options and builds the package, and tries to install it, "make install" will
return an error since the non-root user will not have "write" permission to
/usr/include/sysfs to install the headers.
However, the library and binaries will be installed at the requested location.
The header files will have to be manually copied over by the user to the
desired directory.
