TCP/IP Programming Manual

disconnect occurs before the end of file, FTP throws all the data away. FTP is still useful because
in fact, loss of connection does not happen often and the cost of retransmission is not always too
high. However, a transaction is being transmitted, you must know if it got there and was processed.
HP NonStop higher-level protocols frequently used for transaction processing include ODBC and
NonStop CORBA which are request/reply model protocols.
Using LISTNER for Custom Applications
If your application fits the standard listener model (see the TCP/IPv6 Configuration and Management
Manual), you can use LISTNER to start your application programs just like it starts FTPSERV.
Input/Output Multiplexing
Multiplexing is a facility used in applications to transmit and receive I/O requests among multiple
sockets. HP NonStop systems support this facility with nowaited operations which also allow you
to multiplex socket I/O with other kinds of I/O. The new IPv6 library routines have not been
implemented in nowaited form. See Optimal Ways to Deal With Connection Management (page 47)
for information about nowaited operations.)
