CRE-Independent Socket Library
CRE-Independent Socket Library
The CRE-Independent socket library routines are provided in three versions for data
storage. Two are non-native versions, one for the large-memory model and one for the
wide-data model. The large-memory model routines are in the file
$SYSTEM.ZTCPIP.LNETINDL. The wide-data model routines are in
$SYSTEM.ZTCPIP.LNETINDW. The native-linkable version is in the file LNETINDN.
For more details on memory models, refer to the C/C++ Programmer’s Guide.
Summary of Routines
Both sets of the socket library contain two main types of routines: socket routines and
support routines.
Socket routines deal directly with connections and data transfer for NonStop IPX/SPX.
Table 5-1 lists and briefly describes each socket routine and provides the page number
where the routine is described.

Name and
Description Page Function Page
accept
Listens for connections on an existing socket,
creates a new socket for data transfer, and
accepts a connection on the new socket (waited)
5-10
accept_nw Listens for connections on an existing socket
(nowait)
5-12
accept_nw2 Creates a new socket for data transfer and
accepts a connection on the new socket (nowait)
5-15
bind, bind_nw Binds a socket to an address and port number
(waited or nowait)
5-17
connect, connect_nw Connects a socket to a remote socket (waited or
nowait)
5-20
getpeername,
getpeername_nw
Gets the address and port number of a remote
host (waited or nowaited)
5-23
getsockname,
getsockname_nw
Gets the address and port number to which a
socket is bound (waited or nowait)
