| void deallocate( T* p, std::size_t n ); |
(library fundamentals TS) | |
Deallocates the storage pointed to by p, which must have been allocated from a memory_resource x that compares equal to *resource() using x.allocate(n * sizeof(T), alignof(T)).
Equivalent to this->resource()->deallocate(p, n * sizeof(T), alignof(T));.
Parameters
| p | - | pointer to memory to deallocate |
| n | - | the number of objects originally allocated |
Exceptions
Throws nothing.
