CS_ENDPOINT allows an application to get a file descriptor, the number associated with a connection to a remote server. This may be useful to a gateway application that contains both Client-Library and Server-Library calls: after establishing a connection to a remote server with Client-Library, the file descriptor associated with that connection is used by the srv_poll Server-Library routine. A call to srv_poll causes the current thread to be rescheduled until there are results available on the connection.
Use of the CS_ENDPOINT property is discouraged, since it is currently specific only to UNIX platforms.
