NAME¶

memkind_memtier - memory tiering interface
Note: memkind_memtier.h functionality is considered as stable API (STANDARD API).

SYNOPSIS¶

#include <memkind_memtier.h>

Link with -lmemkind

TIER MANAGEMENT:

struct memtier_builder *memtier_builder_new(memtier_policy_t policy);


void memtier_builder_delete(struct memtier_builder *builder);


int memtier_builder_add_tier(struct memtier_builder *builder, memkind_t kind, unsigned kind_ratio);


struct memtier_memory *memtier_builder_construct_memtier_memory(struct memtier_builder *builder);


void memtier_delete_memtier_memory(struct memtier_memory *memory);

HEAP MANAGEMENT:


void *memtier_malloc(struct memtier_memory *memory, size_t size);


void *memtier_kind_malloc(memkind_t kind, size_t size);


void *memtier_calloc(struct memtier_memory *memory, size_t num, size_t size);


void *memtier_kind_calloc(memkind_t kind, size_t num, size_t size);


void *memtier_realloc(struct memtier_memory *memory, void *ptr, size_t size);


void *memtier_kind_realloc(memkind_t kind, void *ptr, size_t size);


int memtier_posix_memalign(struct memtier_memory *memory, void **memptr, size_t alignment, size_t size);


int memtier_kind_posix_memalign(memkind_t kind, void **memptr, size_t alignment, size_t size);


size_t memtier_usable_size(void *ptr);


void memtier_free(void *ptr);


void memtier_kind_free(memkind_t kind, void *ptr);


size_t memtier_kind_allocated_size(memkind_t kind);
