1 Introduction

                           A few use notes

CAVEAT: On some implementations, the GC takes care of deallocating the
arrays, while on others they need to be deallocated explicitly;
therefore, in order to make sure that deallocation works on all
implementations, you must use FREE-STATIC-VECTOR and make sure that
all references to the array are destroyed.

Furthermore, you can only allocate simple-arrays - not arrays of
element-type T and not multidimensional arrays. For use in the latter case,
you can displace a multidimensional array to a simple-array of element-type.

This library is especially useful in cases when you need to share an
array with a C/C++/Fortran library, as long as the allocation is done
on the Lisp side: e.g. as buffer for an I/O stream, et cætera...

5.1 Exported definitions

5.1.1 Macros

Macro: with-static-vector (VAR LENGTH &rest ARGS &key ELEMENT-TYPE INITIAL-CONTENTS INITIAL-ELEMENT) &body BODY

Bind PTR-VAR to a static vector of length LENGTH and execute BODY within its dynamic extent. The vector is freed upon exit.

Package

static-vectors

Source

impl.lisp (file)

Macro: with-static-vectors ((VAR LENGTH &rest ARGS) &rest MORE-CLAUSES) &body BODY

Allocate multiple static vectors at once.

Package

5.1.2 Functions

Function: fill-foreign-memory POINTER LENGTH VALUE

Fill LENGTH octets in foreign memory area POINTER with VALUE.

Package

static-vectors

Source

impl.lisp (file)

Function: free-static-vector VECTOR

Free VECTOR, which must be a vector created by MAKE-STATIC-VECTOR.

Package

static-vectors

Source

impl.lisp (file)

Function: make-static-vector LENGTH &key ELEMENT-TYPE INITIAL-ELEMENT INITIAL-CONTENTS

Create a simple vector of length LENGTH and type ELEMENT-TYPE which will not be moved by the garbage collector. The vector might be allocated in foreign memory so you must always call FREE-STATIC-VECTOR to free it.

Package

static-vectors

Source

constructor.lisp (file)

Function: replace-foreign-memory DST-PTR SRC-PTR LENGTH

Copy LENGTH octets from foreign memory area SRC-PTR to DST-PTR.

Package

static-vectors

Source

impl.lisp (file)

Function: static-vector-pointer VECTOR &key OFFSET

Return a foreign pointer to the beginning of VECTOR + OFFSET octets. VECTOR must be a vector created by MAKE-STATIC-VECTOR.
