An FLI type which does not have a simple representation in memory and is therefore represented as a "boxed" Lisp object. Arrays, string, structure, and unions are all aggregate types.
A Lisp function, defined with the FLI macro
define-foreign-callable, which can be called from a foreign language.
A coerced pointer is a pointer that is dereferenced with the
:type key in order to return the value pointed to as a different type than specified by the pointer type. For example, a pointer to a byte can be coerced to return a boolean on dereferencing.

A function in the
fli package used to interface Lisp with a foreign language.
A data type specifier in the
fli package used to define data objects that interface between Lisp and the foreign language. For example, a C
long might be passed to LispWorks through an instance of the FLI type
:long, from which it is transferred to a Lisp
See callable function.
A Lisp function, defined using the FLI macro
define-foreign-function, which calls a function written in a foreign language. A foreign function contains no body, consisting only of a name and a list of arguments. The function in the foreign language provides the body of the foreign function.
A language to which Lisp can be interfaced using the FLI. Currently the FLI interfaces to C, and therefore also the Win32 API functions.
An FLI type that can be represented within a single register of memory. Immediate types include all integer, floating point, character, byte, and boolean types.
An FLI type consisting of an address and a type specification. A pointer normally points to the memory location of an instance of the type specified, although there might not actually be an allocated instance of the type at the pointer location.
A description of the
:wrapper FLI type which "wraps" around an object, allowing data to be passed to or obtained from the object as though it was of a different type. A wrapper can be viewed as a set of conversion functions defined on the object which are automatically invoked when the wrapped object is accessed.
