Session Manager Proxy

## NAME

smproxy - Session Manager Proxy

## SYNOPSIS

**smproxy** \[**-clientId** *id*\] \[**-restore** *saveFile*\] \[**-version**\]

## OPTIONS

- **-clientId *id***

  Specifies the session ID used by **smproxy** in the previous session.

- **-restore *saveFile***

  Specifies the file used by **smproxy** to save state in the previous session.

- **-version**

  Prints the program version and exits.

## DESCRIPTION

**smproxy** allows X applications that do not support X11R6 session management to participate in an X11R6 session.

In order for **smproxy** to act as a proxy for an X application, one of the following must be true:

- –

  The application maps a top level window containing the **WM\_CLIENT\_LEADER** property. This property provides a pointer to the client leader window which contains the **WM\_CLASS**, **WM\_NAME**, **WM\_COMMAND**, and **WM\_CLIENT\_MACHINE** properties.

or

- –

  The application maps a top level window which does not contain the **WM\_CLIENT\_LEADER** property. However, this top level window contains the **WM\_CLASS**, **WM\_NAME**, **WM\_COMMAND**, and **WM\_CLIENT\_MACHINE** properties.

An application that support the **WM\_SAVE\_YOURSELF** protocol will receive a **WM\_SAVE\_YOURSELF** client message each time the session manager issues a checkpoint or shutdown. This allows the application to save state. If an application does not support the **WM\_SAVE\_YOURSELF** protocol, then the proxy will provide enough information to the session manager to restart the application (using **WM\_COMMAND**), but no state will be restored.
