std::pmr::polymorphic_allocator<T>::deallocate_bytes
void deallocate_bytes( void* p,
std::size_t nbytes,
std::size_t alignment = alignof(std::max_align_t) ); |
(since C++20) |
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).
Equivalent to resource()->deallocate(p, nbytes, alignment);
Parameters
| p | - | pointer to memory to deallocate |
| nbytes | - | the number of bytes originally allocated |
| alignment | - | the alignment originally allocated |
Exceptions
Throws nothing.
Notes
This function was introduced for use with the fully-specialized allocator std::pmr::polymorphic_allocator<>, but it may be useful in any specialization.
