This class is used to allocate bytes of memory from a pool that is never intended to be freed.
It is particularly useful to support DeletedChain, which allocates memory in just such a fashion.
When it is known that memory will not be freed, it is preferable to use this instead of the standard malloc() (or global_operator_new()) call, since this will help reduce fragmentation problems in the dynamic heap. Also, memory allocated from here will exhibit less wasted space.
static unsigned int getTotalAlloc | ( | ) | [static] |
Returns the total number of bytes consumed by all the pages allocated internally by this object.
static unsigned int getTotalUnused | ( | ) | [static] |
Returns the difference between get_total_alloc() and get_total_used().
This represents bytes in allocated pages that have not (yet) been used by the application.
static unsigned int getTotalUsed | ( | ) | [static] |
Returns the total number of bytes requested by the application in calls to NeverFreeMemory.alloc().
