std::pmr::polymorphic_allocator<T>::allocate_bytes

void * allocate_bytes( std::size_t nbytes, std::size_t alignment = alignof( std::max_align_t ) ) ;		(since C++20)

Allocates nbytes bytes of storage at specified alignment alignment using the underlying memory resource. Equivalent to return resource( ) - >allocate(nbytes, alignment) ;

Parameters

nbytes	-	the number of bytes to allocate
alignment	-	the alignment to use

Return value

A pointer to the allocated storage.

Notes

This function was introduced for use with the fully-specialized allocator std::pmr::polymorphic_allocator <>

The return type is void* (rather than, e.g., std::byte*) to support conversion to an arbitrary pointer type U* by static_cast<U*>

Exceptions

May throw any exceptions thrown by the call to resource()->allocate
