# publicVariableServer

## Category
Multiplayer

## Arity
**Unary** — `publicVariableServer "<variableName>"`.

```
publicVariableServer <string>   // quoted variable name
```

## Description
Sends the value of a global variable to the **server only** (not to other clients). The variable name is passed as a string. Useful for clients sending data to the server without broadcasting to everyone.

**Placeholder/stub** — full networking implementation is the host's responsibility.

## How It Works
Fires the host's public variable event targeted at the server only. More efficient than `publicVariable` when only the server needs the update.

## Usage

```sqf
// Client sends request to server
_playerAction = "ready";
publicVariableServer "_playerAction";

// Client reports position to server
_clientPos = [1234, 5678, 0];
publicVariableServer "_clientPos";
```

## Thread Safety
Depends on host implementation.
