[section:SyncWriteStream Buffer-oriented synchronous write stream requirements]
A type `X` meets the `SyncWriteStream` requirements if it satisfies the
requirements listed below.
In the table below, `a` denotes a value of type `X`, `cb` denotes a (possibly
const) value satisfying the [link asio.reference.ConstBufferSequence
`ConstBufferSequence`] requirements, and `ec` denotes an object of type
`error_code`.

write operation].[br]
[br]
If `buffer_size(cb) > 0`, writes one or more bytes of data to the stream
`a` from the buffer sequence `cb`. If successful, sets `ec` such that
`!ec` is `true`, and returns the number of bytes written. If an error
occurred, sets `ec` such that `!!ec` is `true`, and returns 0.[br]
[br]
If `buffer_size(cb) == 0`, the operation shall not block. Sets `ec` such
that `!ec` is `true`, and returns 0.
