Yes and no -- not builtin, but you can use the code below. (define-alien-variable ("dynamic_space_size" dynamic-space-size-bytes) unsigned-long) (defun heap-n-bytes () (+ dynamic-space-size-bytes (- sb-vm::read-only-space-end sb-vm::read-only-space-start) (- sb-vm::static-space-end sb-vm::static-space-start))) > 2) Can I change this heap size in a running SBCL? Not currently. > 3) Does the command line argument '--dynamic-space-size' set this heap > size (or at least part of it)? Yes (part of of it.) > 3b) Do you really state the space size in MBytes (as in > --dynamic-space-size 250)? I pretty much got a "heap exhausted" message > right away. Having --dynamic-space-size 250.000.000 seems to work much > better... Yes, it is in megabytes. The number of bytes used is (strtol(arg,0 ,0) << 20). > 4) Finally (and possibly stupid, but since I'm at it): do these command > line arguments also work when setting SBCL as inferior lisp in SLIME > (yes, I admit I haven't checked any manual w.r.t. this: mea culpa) Yes (well, assuming Emacs passes them to SBCL when it invokes it.)
