, this prints the memory allocation, in bytes, made during a function call. The symbol that
evaluates to is used to accumulate the amount of memory allocated between entering and exiting the traced function.
Note that this symbol continues to be used as an accumulator on subsequent calls to the traced function; the value is compounded, rather than over-written.
Consider the example below:
facfunction, set the value of
fac, and then examine the value of
CL-USER 152 > $$fac-alloc
