[section:ConstBufferSequence Constant buffer sequence requirements]
|
||
|
|
|
||
|
|
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.

||
