# CreateNativeUiHostCapabilities

Create native ui host capabilities from the supplied values.

Package: host.ui_services | Status: source-declared

Tags: cpu, function, host, host.ui_services, source-example, ui_services, yeho

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

```yh
external CreateNativeUiHostCapabilities(text provider, bool accessibility, bool textInput, bool clipboard, bool displayTopology, bool sessionLifecycle, bool virtualKeyboard, bool delayedClipboard) returns nativeUiHostCapabilityRecord
```


## Use CreateNativeUiHostCapabilities

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 provider = "provider"
bool accessibility = true
bool textInput = true
bool clipboard = true
bool displayTopology = true
bool sessionLifecycle = true
bool virtualKeyboard = true
bool delayedClipboard = true
nativeUiHostCapabilityRecord result = CreateNativeUiHostCapabilities(provider, accessibility, textInput, clipboard, displayTopology, sessionLifecycle, virtualKeyboard, delayedClipboard)
Console.Log("Inspect result in your debugger")

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.host_ui_services__createnativeuihostcapabilities"
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--CreateNativeUiHostCapabilities/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.
