package sys-socket

sys-socket

This module provides OCaml ctypes bindings to system-specific low-level socket structure and data-types.

The interface is implemented using ocaml-ctypes and is intended to exposed the machine-specific, low-level details of the most important parts of socket implementations.

Sys_socket provides an API compatible for both Unix and Win32 systems, while Sys_socket_unix provides the API specific to Unix systems, mostly the sockaddr_u structure.

On POSIX systems, the following headers define the bound types and structures:

• sys/sock.h
• sys/un.h
• netinet/in.h

On windows systems, the following headers define the bound types and structures:

• winsock.h
• ws2tcpip.h

Its API mirrors as much as possible the original POSIX definitions, including integers representation (network bytes order, host byte order). It is defined in sys_socket.mli

A high-level wrapper for the OCaml Unix module is provided as well.

Happy hacking!
