type: function (subr) location: built-in source file: xldmem.c Common LISP compatible: yes supported on: all machines
The GC function forces a garbage collection of the unused memory of XLISP. NIL is always returned.
(gc) ; force a garbage collection
NOTE: The system will cause an automatic garbage collection if it runs out of free memory.
NOTE: When GC is called or an automatic garbage collection occurs, if the amount of free memory is still low after the garbage collection, the system attempts to add more segments (an automatic EXPAND).
