- * The request structure declared below is used by the XENIX 286 emulator

- * executable's private data.

- * If the 'xsd_cmd' field is SI86SHR_SZ, the XENIX 286 emulator is using the
- * SI86SHRGN subcommand to retrieve the size of an existing XENIX shared
- * data segment. In this case, the xsdbuf struct contains the start addr
- * for the shared data in 386 space.
