std::pmr::polymorphic_allocator<T>::deallocate_bytes

Deallocates the storage pointed to by p, which must have been allocated from a std::pmr::memory_resource x that compares equal to *resource(), using x.allocate(nbytes, alignment), typically through a call to allocate_bytes(nbytes, alignment).

# Declarations

void deallocate_bytes( void* p,
std::size_t nbytes,
std::size_t alignment = alignof(std::max_align_t) );

(since C++20)

# Parameters

• p: pointer to memory to deallocate
• nbytes: the number of bytes originally allocated
• alignment: the alignment originally allocated

# Notes

This function was introduced for use with the fully-specialized allocator std::pmr::polymorphic_allocator<>, but it may be useful in any specialization.
