Memavail is the dynamic memory available to the heapmanager. But that is potentially decreased by code,stack and (static) data segment and startup allocations.

Anyway, these functions get info from the heapmanager, so the bit that is interesting is how the RTL finds the amount of memory and initializes the heapmanage)
