buffers_prefix (3 of 3 overloads)

buffers_prefix (3 of 3 overloads)

Returns a prefix of a buffer sequence.

Synopsis

Defined in header <boost/beast/core/buffers_prefix.hpp>

template<
    class BufferSequence>
buffers_prefix_view< BufferSequence >
buffers_prefix(
    std::size_t size,
    BufferSequence const& buffers);

Description

This function returns a new buffer sequence which when iterated, presents a shorter subset of the original list of buffers starting with the first byte of the original sequence.

Parameters

Name	Description
`size`	The maximum number of bytes in the wrapped sequence. If this is larger than the size of passed, buffers, the resulting sequence will represent the entire input sequence.
`buffers`	An instance of ConstBufferSequence or MutableBufferSequence to adapt. A copy of the sequence will be made, but ownership of the underlying memory is not transferred.
