1 Introduction

Introduction

The deoxybyte-unix system provides access to Unix functions via CFFI.

Some, but not all, Lisp implementations provide their own POSIX or
Unix package. While deoxybyte-unix treads some well-worn ground in
that respect, it should be portable to all Unix platforms supported by
CFFI.

Installation

deoxybyte-unix uses ASDF for system definition. Copy or symlink
deoxybyte-unix.asd (and optionally deoxybyte-unix-test.asd) to your
asdf:*central-registry* and load deoxybyte-unix with the asdf:operate
function:

 (asdf:operate 'asdf:load-op :deoxybyte-unix)

or with the equivalent deoxybyte-systems:load-system function:

 (dxs:load-system :deoxybyte-unix)


Tests

To run the unit and regression tests you need to have LIFT
installed. Run the tests with the asdf:operate function:

 (asdf:operate 'asdf:test-op :deoxybyte-unix)

or with the equivalent deoxybyte-systems:test-system function:

 (dxs:test-system :deoxybyte-unix)


Documentation

See the Lisp docstrings, particularly the package docstrings for an
overview. HTML documentation may be generated with the command:

 (dxs:document-system :deoxybyte-unix)

at the REPL, provided that CLDOC is installed.

5.1 uk.co.deoxybyte-unix

The deoxybyte-unix package provides a Lisp style
interface to the low level FFI in the :deoxybyte-unix-ffi package.

Some, but not all, Lisp implementations provide a POSIX or Unix package. While deoxybyte-unix treads some well-worn ground in that respect, it should be portable to all Unix platforms supported by CFFI.

5.2 uk.co.deoxybyte-unix-ffi

The deoxybyte-unix-ffi package provides utility
foreign functions to Unix via CFFI. This is a low-level FFI that does not provide a Lisp-style layer on top of the basic Unix functions. A small subset of Unix functionality is represented, with further functions being added as required.

Function: mmap FILESPEC &key LENGTH FOREIGN-TYPE PROTECTION

Maps a file into memory.

Arguments:

- filespec (pathname designator): The file to be mmapped.

Key:

- foreign-type (symbol): The foreign type of the elements to be stored in the vector.
- protection (list symbol): The memory protection keyword flags used in the mmap operation.

Returns:
