NAME
std::pmr::polymorphic_allocator<T>::allocate - std::pmr::polymorphic_allocator<T>::allocate
Synopsis
T* allocate( std::size_t n ); (since C++17)
[[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)));.
Parameters
n - the number of objects to allocate storage for
Return value
A pointer to the allocated storage.
Exceptions
Throws std::length_error if n > SIZE_MAX / sizeof(T); may also any exceptions thrown by the call to resource()->allocate.
