The function
count-gen-num-allocation
returns the amount of allocated data in generation
gen-num
. If
include-lower-generations
is non-nil, the returned value
allocation
also includes the data in the younger generations.
count-gen-num-allocation
is implemented only in 64-bit LispWorks. It is not relevant to the Memory Management API in 32-bit implementations, where you can use room-values instead.
