SYNOPSIS¶

#include <pmem_allocator.h>

Link with -lmemkind

pmem::allocator(const char *dir, size_t max_size)


pmem::allocator(const std::string& dir, size_t max_size)


template <typename U> pmem::allocator<T>::allocator(const pmem::allocator<U>&) noexcept


template <typename U> pmem::allocator(const allocator<U>&& other) noexcept


pmem::allocator<T>::~allocator()


T* pmem::allocator<T>::allocate(std::size_t n) const


void pmem::allocator<T>::deallocate(T* p, std::size_t n) const


template <class U, class... Args> void pmem::allocator<T>::construct(U* p, Args... args) const


void pmem::allocator<T>::destroy(T* p) const

DESCRIPTION¶

All public member types and functions corresponds to standard library allocator concepts and definitions. The current implementation supports C++11 standard.

Template arguments:
T is an object type aliased by value_type.
U is an object type.

Note:
T* pmem::allocator<T>::allocate(std::size_t n) allocates persistent memory memory using memkind_malloc(). Throw std::bad_alloc when:
n = 0,
or there is not enough memory to satisfy the request.

void pmem::allocator<T>::deallocate(T* p, std::size_t n) deallocates memory associated with pointer returned by allocate() using memkind_free().

To find out more about memkind_malloc() and memkind_free() read memkind(3) man page.
