Detailed Description

template<typename... Options>
struct cds::memory::michael::Heap< Options >::processor_heap_base

Processor heap.

Field Documentation

template<typename... Options>

const unsigned int cds::memory::michael::Heap< Options >::processor_heap_base::c_nPageSelfAllocation = (unsigned int) -1

static

Small page marker.

If page is small and can be allocated by the Heap, the nPageIdx value is c_nPageSelfAllocation. This optimization allows to allocate system memory more regularly, in blocks of 1M that leads to less memory fragmentation.

template<typename... Options>

CDS_DATA_ALIGNMENT (8) std processor_desc* cds::memory::michael::Heap< Options >::processor_heap_base::pProcDesc

< pointer to the descriptor of active superblock owned by processor heap

pointer to parent processor descriptor
