get-gc-parameters

get-gc-parameters Function

Summary

Returns the current values of various garbage collector parameters in 32-bit LispWorks.

Package

hcl

Signature

get-gc-parameters parameters => values

Arguments

parameters⇩

A keyword representing a single GC parameter. Any other value means all parameters.

Values

values

If parameters specifies a single GC parameter, the value of that parameter is returned. Otherwise values is an alist containing every GC parameter, together with its current value.

Description

The function get-gc-parameters returns the current values of the garbage collector parameters in 32-bit LispWorks specified by parameters. See set-gc-parameters for a full description of these parameters.

With keyword argument, of one of the parameters, the corresponding value is returned.

Notes

get-gc-parameters is implemented only in 32-bit LispWorks. It is not relevant to the Memory Management API in 64-bit implementations.
