Udp socket open.

Package: network.udp | Status: source-declared

Tags: cpu, function, network, network.udp, source-example, udp, yeho

Exchange bounded UDP datagrams; your application owns its protocol and session rules.

```yh
external UdpSocketOpen(udpSocket socket) returns bool
```


## Use UdpSocketOpen

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using network.udp

// Exchange bounded UDP datagrams; your application owns its protocol and session rules.
udpSocket socket = udpSocket(1, 1)
bool result = UdpSocketOpen(socket)
Console.Log(Text.From(result))

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.network_udp__udpsocketopen"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]
kind = "headless"

[[dependencies]]
package = "network.udp"
version = "0.1.0"
path = "../../../yeho/packages/network/udp"

```

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.

```sh
./yeho/build/dolphin-metal/yehoc ./api-examples/network.udp--UdpSocketOpen/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
