trimcore/0trimcore
Force reclamation of memory in all of Prolog’s data areas.
Trims the stacks, reclaims any dead clauses and predicates, defragmentizes Prolog’s free memory, and endeavors to return any unused memory to the operating system.
The system property
PROLOGKEEPSIZE can be used to define a lower bound on the amount
of memory to be retained. Also, the system property
PROLOGINITSIZE can be used to request that an initial amount of
memory be allocated. This initially allocated memory will not be touched
by trimcore/0.
When trimming a given stacks, trimcore/0 will retain at least
the amount of space initially allocated for that stack.
trimcore/0 is called each time Prolog returns to the
top level or the top of a break level, except it does not trim the stacks then.
None.
