SOCKETS(BS2000) interface for an external bourse

This chapter describes the additional functions of the socket interface for BS2000 in the special mode for using an external bourse. This makes it possible to coordinate various events by specifying an external bourse with a common wait point.

The socket mode (external wait point or not) is set with the first socket call and is then static. The setting is made with a setsockopt() subfunction.

The additional function soc_getevent() and the subfunction SO_ASYNC for setsockopt() are provided to achieve this functionality.
