std::pmr::polymorphic_allocator<T>::deallocate_bytes
From cppreference.com
< cpp | memory | polymorphic allocator
void deallocate_bytes( void* p, std::size_t nbytes, |
(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 resorce()->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::polymorphic_allocator<>, but it may be useful in any specialization.
