Sockets with std.net in Zig 0.13.0

[Sze]

I haven’t really used it a lot yet, but these topics seem related:

Is this error expected?

const std = @import("std"); const net = std.net; const posix = std.posix; const mem = std.mem; pub fn main() !void { var addr = try net.Address.parseIp("127.0.0.1", 33333); const socket_fd = try posix.socket(addr.any.family, posix.SOCK.STREAM, posix.IPPROTO.TCP); const socket_len: posix.socklen_t = addr.getOsSockLen(); try posix.setsockopt( socket_fd, posix.SOL.SOCKET, posix.SO.REUSEADDR, &mem.toBytes(@as(c_int, 1)), ); try posix.bind(s…

This one is a bit older, back then a bunch of functions were in std.os that are now in std.posix:

UDP Socket Server in Zig

The following is a working example that wait for one packet, displays it and exits. const std = @import("std"); pub fn main() !void { const addr = try std.net.Address.parseIp("127.0.0.1", 55555); const sock = try std.os.socket(std.os.AF.INET, std.os.SOCK.DGRAM, std.os.IPPROTO.UDP); defer std.os.close(sock); try std.os.bind(sock, &addr.any, addr.getOsSockLen()); var buf: [1024]u8 = undefined; const len = try std.os.recv(sock, &buf, 0); std.debug.print("{s}\n", .{buf[…

I think for these sorts of things the cookbook is often a good starting point:
