Pointer based primitive for handling memory

#include <memory>
template <class T>
pair<T*, ptrdiff_t> get_temporary_buffer (ptrdiff_t);
template <class T>
pair<T*, ptrdiff_t> get_temporary_buffer (ptrdiff_t, T*);

The get_temporary_buffer templatized function reserves from system memory the largest possible buffer that is less than or equal to the size requested (n*sizeof(T)), and returns a pair<T*, ptrdiff_t> containing the address and size of that buffer. The units used to describe the capacity are in sizeof(T).

The first version of this function is not available if your compiler does not support functions templatized on return type only.
