T* allocate( std::size_t n ); | (since C++17) (until C++20) | |
[[nodiscard]] T* allocate( std::size_t n ); | (since C++20) |
Allocates storage for n
objects of type T
using the underlying memory resource. Equivalent to return static_cast<T*>(resource()->allocate(n * sizeof(T), alignof(T)));
.
n | - | the number of objects to allocate storage for |
A pointer to the allocated storage.
Throws std::length_error
if n > SIZE_MAX / sizeof(T)
; may also any exceptions thrown by the call to resource()->allocate
.
(C++20) | Allocate raw aligned memory from the underlying resource (public member function) |
(C++20) | Allocates raw memory suitable for an object or an array (public member function) |
(C++20) | Allocates and constructs an object (public member function) |
[static] | allocates uninitialized storage using the allocator (public static member function of std::allocator_traits<Alloc> ) |
allocates memory (public member function of std::pmr::memory_resource ) |
