jsocketpp::BufferView Struct Reference

Represents a raw writable memory region for scatter/gather I/O. More...

#include <BufferView.hpp>

Public Attributes
void *	data {}
	Pointer to the writable memory region.
std::size_t	size {}
	Size in bytes of the writable region.

Detailed Description

Represents a raw writable memory region for scatter/gather I/O.

BufferView is used to describe non-contiguous writable memory ranges for use with vectorized socket operations (e.g., readv, writev, readvAll).

It allows efficient I/O without copying or concatenating buffers, enabling zero-copy messaging and protocol framing.

Fields

• data: Pointer to writable memory
• size: Size in bytes of the memory region

Example Usage

std::array<std::byte, 4> header;
std::array<std::byte, 128> payload;
std::array<jsocketpp::BufferView, 2> views = {
    jsocketpp::BufferView{header.data(), header.size()},
    jsocketpp::BufferView{payload.data(), payload.size()}
};
socket.readvAll(views);
