libmemkind::fixed::allocator<T>
- The C++ allocator compatible with the C++ standard library
allocator concepts

(STANDARD API).

The libmemkind::fixed::allocator<T> is intended to be used with STL containers to allocate memory on specific area. Memory management is handled by jemalloc on the supplied area. Refer memkind(3) man page for more details.
All public member types and functions correspond 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
*libmemkind::fixed::allocator<T>::allocate(std::size_t
n) allocates memory using
memkind_malloc() on the area supplied to
libmemkind::fixed::allocator(). Throws
std::bad_alloc when:
n = 0
or there is not enough memory to satisfy the request.
libmemkind::fixed::allocator<T>::deallocate(T *p, std::size_t n) deallocates memory associated with pointer returned by allocate() using memkind_free().
