◆ MallocUsage()

static size_t memusage::MallocUsage ( size_t  alloc)
inlinestatic

Compute the total memory used by allocating alloc bytes.

Compute the memory used for dynamically allocated but owned data structures.

For generic data types, this is not recursive. DynamicUsage(vector<vector<int> >) will compute the memory used for the vector<int>'s, but not for the ints inside. This is for efficiency reasons, as these functions are intended to be fast. If application data structures require more accurate inner accounting, they should iterate themselves, or use more efficient caching + updating on modification.
