gc-parameter

Arguments: gc-parameter

This function returns the current value of the parameter gc-parameter. Where appropriate, it can be used with setf to set the parameter value:

cg-user(16): (sys:gc-parameter :free-percent-new)
25
cg-user(17): (setf (sys:gc-parameter :free-percent-new) 30)
30
cg-user(18): (sys:gc-parameter :free-percent-new)
30

The function sys:gc-switch performs the same role for switches. The function sys:gc-parameters prints all switches and parameters along with their current values.

See gc.htm for more information on the garbage collector. The section System parameters and switches in that document describes all parameters and switches.
