Define host text, editing, clipboard, and accessibility service contracts.

```yh
external CreateNativeUiDisplay(text id, int x, int y, int width, int height, int workX, int workY, int workWidth, int workHeight, int scalePercent, bool primary) returns nativeUiDisplayRecord
```


## Use CreateNativeUiDisplay

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

Verification: type checked

```yh
using host.ui_services

// Define host text, editing, clipboard, and accessibility service contracts.
text id = "id"
int x = 1
int y = 1
int width = 1
int height = 1
int workX = 1
int workY = 1
int workWidth = 1
int workHeight = 1
int scalePercent = 1
bool primary = true
nativeUiDisplayRecord result = CreateNativeUiDisplay(id, x, y, width, height, workX, workY, workWidth, workHeight, scalePercent, primary)
Console.Log("Inspect result in your debugger")

```

Save this beside start.yh as project.mech:

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

[app]
kind = "headless"

[[dependencies]]
package = "host.ui_services"
version = "0.1.0"
path = "../../../yeho/packages/host/ui_services"

```

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/host.ui_services--CreateNativeUiDisplay/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.
