std::pmr::memory_resource::allocate - std::pmr::memory_resource::allocate


void* allocate(std::size_t bytes, (since C++17)
std::size_t alignment = alignof(std::max_align_t)); (until C++20)
[[nodiscard]] void* allocate(std::size_t bytes, (since C++20)
std::size_t alignment = alignof(std::max_align_t));

Allocates storage with a size of at least bytes bytes. The returned storage is aligned to the specified alignment if such alignment is supported, and to alignof(std::max_align_t) otherwise.
Equivalent to return do_allocate(bytes, alignment);.


Throws an exception if storage of the requested size and alignment cannot be obtained.
