A constant buffer sequence represents a set of memory
regions that may be used as input to an operation, such as the send
operation of a socket.
A type X
meets the ConstBufferSequence
requirements if it
satisfies the requirements of Destructible
(C++Std [destructible]) and CopyConstructible
(C++Std [copyconstructible]), as well as the additional requirements listed
below.
In the table below, x
denotes
a (possibly const) value of type X
,
and u
denotes an identifier.
