Outdated egg!

This is an egg for CHICKEN 4, the unsupported old release. You're almost certainly looking for the CHICKEN 5 version of this egg, if it exists.

If it does not exist, there may be equivalent functionality provided by another egg; have a look at the egg index. Otherwise, please consider porting this egg to the current version of CHICKEN.

Usage Example

 (use proccpuinfo)
 (proccpuinfo 'architecture)
 (proccpuinfo 'hardware-platform)
 (proccpuinfo 'frequency)
 (proccpuinfo 'bogomips)
 (proccpuinfo 'cache)
 (proccpuinfo 'cpus)
 (proccpuinfo 'cputype)



The proccpuinfo egg is maintained in a Gitorious repository


This egg contains thoroughly commented Chicken code (mainly in the "proccpuinfo.scm" file) which is intended to be an example of how a basic Chicken binding of a simple C library can be created.


This binding is distributed as a Chicken egg. To compile and install this egg, you must first download and install libproccpuinfo.

libproccpuinfo can be downloaded from here.

Its documentation can be found here.

Once you've installed libproccpuinfo, you can compile and install this egg by typing:

 chicken-install proccpuinfo


 This egg has only been tested with libproccpuinfo version 0.0.8

Troubleshooting tips

If you receive an error from chicken-install about not being able to find "proccpuinfo.h" or about not being able to find "-lproccpuinfo", try passing the locations of libproccpuinfo's header and library files to chicken-install via your shell's CFLAGS and LDFLAGS environment variables.

For example, you could try running something like the following from your shell:

 CFLAGS=-I/usr/local/libproccpuinfo/include LDFLAGS=-L/usr/local/libproccpuinfo/lib chicken-install proccpuinfo

Substitute the path you've installed libproccpuinfo to in place of "/usr/local/libproccpuinfo"

List of Procedures

This egg only exports a single procedure:

[procedure] (proccpuinfo DESIRED-INFO [filename: FILENAME] [arch: ARCHITECTURE])

Where DESIRED-INFO is one of the following:

and FILENAME is an optional string containing the name of the file to read from instead of the default "/proc/cpuinfo"

and ARCHITECTURE is an optional string that will be used to interpret the cpuinfo file as if it was read on a different architecture.

This procedure will return the desired entry from "/proc/cpuinfo" or the given FILENAME, or #f if there is no such entry.

Please see the libproccpuinfo documentation for more information.

Internal Binding Documentation

Please see the comments in the source (the "proccpuinfo.scm" file in particular) for a detailed explanation of how the binding works. A tutorial article regarding this binding is forthcoming. Watch this space.
