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

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.

Example

CL-USER 1 > (get-gc-parameters :minimum-overflow)

500000

CL-USER 2 > (pprint (get-gc-parameters t))

((:ENLARGE-BY-SEGMENTS . 10)

 (:MINIMUM-FOR-PROMOTE . 1000)

 (:MAXIMUM-OVERFLOW . 1000000)

 (:MINIMUM-OVERFLOW . 500000)

 (:MINIMUM-BUFFER-SIZE . 200)

 (:NEW-GENERATION-SIZE . 262144)

 (:PROMOTE-MAX-BUFFER . 100000)

 (:PROMOTE-MIN-BUFFER . 200)

 (:MAXIMUM-BUFFER-SIZE . 131072)

 (:MINIMUM-FOR-SWEEP . 8000)

 (:BIG-OBJECT . 131072))
