netio #

Networking Library for V

netio is a flexible networking library for V programming language.

This module provides the low-level wrappers around C APIs and supports any kind of sockets, socket options, address families and protocols. netio.protocol submodule provides access to the operatins system protocols database.

netio is tested only on Linux, but should work on all POSIX-compliant operating systems. Microsoft Windows support is not planned yet.

See examples/ dir in source code repository for usage examples.

fn addr_info #

fn addr_info(hints AddrInfoParams) ![]AddrInfo

addr_info translates the network addresses and services. This is a low-level wrapper around the getaddrinfo(3) C API.

fn find_network_interface #

fn find_network_interface(s string) !NetworkInterfaceId

find_network_interface returns the network interface index and name by provided string s. If network interface is not present the NetworkInterfaceNotFound error will be returned. See also index_to_name() and name_to_index().

Examples

assert netio.find_network_interface('eth0')!.index == 2

fn name_to_index #

fn name_to_index(name string) !u32

name_to_index translates the network interface name to index. See also if_nametoindex(3p).

fn network_interfaces #

fn network_interfaces() ![]NetworkInterfaceId

network_interfaces returns an array with names and indexes of all network interfaces on system. See also if_nameindex(3p).

fn Socket.new #

fn Socket.new(domain AddrFamily, st SocketType, proto Protocol) !Socket

Socket.new creates the new socket. See socket(7) and socket(3) for details.

fn SocketAddr.from_ptr #

unsafe
fn SocketAddr.from_ptr(ptr voidptr, size isize) !SocketAddr

SocketAddr.from_ptr creates new socket address from specified pointer.

Note: Data is reused, not copied.

fn SocketAddr.from_ptr_copy #

unsafe
fn SocketAddr.from_ptr_copy(ptr voidptr, size isize) !SocketAddr

SocketAddr.from_ptr_copy creates new socket address by copying data from specified pointer.

fn SocketAddr.new #

unsafe
fn SocketAddr.new(af AddrFamily, size isize) SocketAddr

SocketAddr.new creates new instance of SocketAddr with specified address family and size.

This function allocates memory (zero filled) for the address, but does not initialize the address itself, you need to do that manually. The benefit is that you can create the any kind of socket address.

SocketAddr is a builder for sockaddr(3type) objects. Use this function only if you understand what you do. Using the write() method you must write the data for the desired socket address, ensuring the correct sizes of all types, the order of the fields in the struct, the byte order, and the total size of the struct. The sizes and byte order may vary by platform, so you'll need to keep an eye on that as well. A mistake while creating an address will crash your application. So this function is marked as unsafe.

The example below creates a sockaddr_in struct describing the loopback IPv4-address 127.0.0.1 with port number 1080. Note the comment in the example. This is a fragment of sockaddr_in(3type) manual page, which shows the target C struct. Summing the field sizes yields 8 bytes, but we need to allocate 16 bytes according to the <netinet/in.h>. Data must be padded to sockaddr struct size which is 16 bytes. Each field is then written in turn, from top to bottom. Keep in mind that two-byte address family field (sin_family in this case) is already written. According to the manual page, the address and port are written using the network (big-endian) byte order.

Example

import encoding.binary
import netio

// struct sockaddr_in {
//     sa_family_t     sin_family;     /* AF_INET */
//     in_port_t       sin_port;       /* Port number */
//     struct in_addr  sin_addr;       /* IPv4 address */
// };
//
// struct in_addr {
//     in_addr_t s_addr;
// };
//
// typedef uint32_t in_addr_t;
// typedef uint16_t in_port_t;

}
