gc-if-needed Function

Summary

Garbage collects if the previous call requires more space that is actually available in 32-bit LispWorks.

Package

hcl

Signature

gc-if-needed => nil

Description

The function gc-if-needed checks to see if the amount of allocation from the previous call is more than system:*allocation-interval*, and if it is, performs a mark and sweep and promotion on generation 0. It also tries to reduce the big-chunk area. This is a fairly brief operation, and can be used whenever some operation is finished and may have left some garbage. The system itself uses it after compiling and loading files, when waiting for input, etc.

Notes

gc-if-needed does nothing in 64-bit LispWorks.
