A dynamic buffer encapsulates memory storage that may be automatically resized as required.
A dynamic buffer type X
shall satisfy the requirements of CopyConstructible
(C++ Std, [copyconstructible]) types in addition to those listed below.
In the table below, X
denotes a dynamic buffer class, x
denotes a value of type X&
, x1
denotes values
of type const X&
, pos
and n
denote
values of type size_t
, and u
denotes an identifier.
