NAME

6       libmemkind::fixed::allocator<T> - The C++ allocator compatible with the
7       C++ standard library allocator concepts
8       Note: fixed_allocator.h is a part of stable API (STANDARD API).

DESCRIPTION

25       The libmemkind::fixed::allocator<T> is intended to  be  used  with  STL
26       containers  to  allocate  memory on specific area. Memory management is
27       handled by jemalloc on the supplied area. Refer memkind(3) man page for
28       more details.
29
30       All  public  member  types and functions correspond to standard library
31       allocator concepts and definitions. The current implementation supports
32       C++11 standard.
33
34       Template arguments:
35       T is an object type aliased by value_type.
36       U is an object type.
37
38       Note:
39       T  *libmemkind::fixed::allocator<T>::allocate(std::size_t  n) allocates
40       memory  using  memkind_malloc()  on   the   area   supplied   to   lib‐
41       memkind::fixed::allocator().  Throws std::bad_alloc when:
42              n = 0
43              or there is not enough memory to satisfy the request.
44
45       libmemkind::fixed::allocator<T>::deallocate(T  *p,  std::size_t  n) de‐
46       allocates memory associated with pointer returned by  allocate()  using
47       memkind_free().
