# XblMultiplayerSessionPropertiesSetReadRestriction

> XblMultiplayerSessionPropertiesSetReadRestriction

Restricts who can read "open" sessions. (Has no effect on reservations, which means it has no impact on "private" and "visible" sessions.)

## Syntax

```cpp theme={null}
void XblMultiplayerSessionPropertiesSetReadRestriction(  
         XblMultiplayerSessionHandle handle,  
         XblMultiplayerSessionRestriction readRestriction  
)  
```

### Parameters

*handle*   \_In\_\
Type: [XblMultiplayerSessionHandle](https://docs.xbox.com/reference/live/xsapi-c/multiplayer_c/handles/xblmultiplayersessionhandle.md)

Handle to the multiplayer session.

*readRestriction*   \_In\_\
Type: [XblMultiplayerSessionRestriction](https://docs.xbox.com/reference/live/xsapi-c/multiplayer_c/enums/xblmultiplayersessionrestriction.md)

New read restriction value.

### Return value

Type: void

## Remarks

Defaults to "none". If "local", only users whose token's DeviceId matches someone else already in the session and "active": true. If "followed", only local users (as defined above) and users who are followed by an existing (not reserved) member of the session can read without a reservation.

## Requirements

**Header:** multiplayer\_c.h

**Library:** Microsoft.Xbox.Services.142.C.lib or Microsoft.Xbox.Services.143.C.lib
