Function

Summary

Allows control over which generation objects are allocated in, in 64-bit LispWorks.

Package

system

Signature

apply-with-allocation-in-gen-num what gen-num func &rest args => results

Arguments

what

One of the keywords :cons, :symbol, :function, :non-pointer and :other.

gen-num

An integer in the inclusive range [0,7], or nil.

func

A function designator.

args

The arguments passed to func.

Values

results

The values returned from the call to func with args.

Description

The function apply-with-allocation-in-gen-num applies the function func to args such that objects of allocation type what are allocated in generation gen-num, in 64-bit LispWorks.

See also the keyword :allocation to make-array, which catches the most common cases.

It is probably quite rare that it is useful to use this function, unless the function allocates a lot, and you are certain that every object that is allocated of the allocation type is long-lived, which is normally difficult to tell.

Notes

1. Allocation of interned symbols is controlled separately by *symbol-alloc-gen-num*.
2. In 32-bit LispWorks the argument what is ignored and the effect is like that of the macro allocation-in-gen-num.
3. In the Mobile GC, gen-num must be 0, 1 or 2.
