Packages are listed by definition order.
uk.co.deoxybyte-unixThe 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.

uk.co.deoxybyte-unix-ffiThe 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.

%var-accessor-*c-error-number* (function).
(setf %var-accessor-*c-error-number*) (function).
Definitions are sorted by export status, category, package, and then by lexicographic order.
Defines a mapped vector class NAME, with accompanying accessor methods ( {defmethod mref} ), specialized to store elements of FOREIGN-TYPE.
Executes BODY in the context of a newly instantiated {defclass mapped-vector} object of CLASS bound to VAR. The vector is safely munmapped after use.
Returns the Unix file descriptor associated with STREAM.
Returns a standard stream (*standard-input* *standard-output* or
*error-output*) if DESIGNATOR is a string that is STRING-EQUAL to one
of "stdin", "stdout" or "stderr", otherwise returns
DESIGNATOR. (Also works for "/dev/stdin" etc.) This function is
useful where one of these strings may be given on a command line to
indicate a system stream, rather than a file-stream is to be used.
Maps a file into memory.
Arguments:
- filespec (pathname designator): The file to be mmapped.
Key:
- length (fixnum): The length of the Lisp vector created when the file
is mmapped.
- 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:
- A pointer.

The mapped file where the error occurred.
:mapped-file
This slot is read-only.
An error that is raised during an index operation on a mmapped file.
An aggregate of data used to describe an mmap operation.
- fr: The mmap file descriptor.
- type: The foreign type in the file being mmapped.
- size: The size in bytes of the region mmapped.
- ptr: The CFFI pointer returned by the mmap foreign function.
- livep: A boolean value which is T if the file is currently mmapped,
or NIL otherwise.

A flag to indicate whether the file

of this slot is set to T.

:length
This slot is read-only.
The mmap-area. This slot symbol is
exported to allow direct access without method
dispatch. This is significantly faster, at least on
SBCL.
:mmap-area

A mapped vector of CHAR.
A mapped vector of DOUBLE.
A mapped vector of FLOAT.

A mapped vector of INT16.
A mapped vector of INT32.
A mapped vector of SHORT.
A mapped vector of UNSIGNED-CHAR.
A mapped vector of UNSIGNED-INT.
A mapped vector of UINT16.
A mapped vector of UINT32.
A mapped vector of UNSIGNED-SHORT.
Performs a bounds check on INDEX with respect to LENGTH. Returns T if 0 <= INDEX < LENGTH, or raises an error otherwise.
Enlarges the open file designated by Unix file descriptor FD to FSIZE bytes.
Returns a new temporary file template string suitable for the C mkstemp function. The template is merged with *default-tmpfile-defaults* to supply the directory component.
