A completion condition is a function object that is
used with the algorithms read, async_read, write, and async_write to determine when the
algorithm has completed transferring data.
A type X meets the CompletionCondition requirements if it
satisfies the requirements of Destructible
(C++Std [destructible]) and MoveConstructible
(C++Std [moveconstructible]), as well as the additional requirements listed
below.
In the table below, x denotes
a value of type X, ec denotes a (possibly const) value of
type error_code, and n denotes a (possibly const) value of type
size_t.
