:lisp-simple-1d-array

FLI type descriptor
Summary

A foreign type which passes the address of a Lisp simple vector direct to C.

Syntax

:lisp-simple-1d-array &optional type

Arguments

type

A list. The default is nil .

Description

:lisp-simple-1d-array is a foreign type which accepts a Lisp simple vector and passes a pointer to the first element of that vector.

The Lisp vector must be simple. That is, it does not have a fill pointer, is not adjustable, and it is not a displaced array.

The Lisp vector as subject to the same memory management restrictions as the array passed with :lisp-array. It must be statically allocated, and may need to be retained explicitly in Lisp.

The argument type , if non-nil, is a list ( element-type &rest dimensions ) and is used to check the element type and dimensions of the Lisp array passed.
