Developing network-based applications

The SCO OpenServer Development System includes libraries that are useful in developing applications that work with various network-oriented communication protocols. These libraries implement the following Application Programming Interfaces (APIs):

• sockets (Internet domain and UNIX domain)

• TLI (SVID3 Transport Library Interface)

• XTI (XPG3 X/Open Transport Interface)

• RPC (Remote Procedure Call)

• XDR (eXternal Data Representation)

• an interface to NIS (Network Information Service)

• an interface to SAPD (Netware Service Access Protocol Daemon)

• an interface to SMUX (SNMP Multiplexing protocol)

• TCP/IP (using sockets, TLI, or XTI)

• NFS (using RPC and XDR)

• NIS (using the Network Information Service library routines)

• IPX/SPX (using TLI)

• the NetWare^® Service Access Protocol daemon, sapd (using the SAPD interface)

• NetBIOS (using XTI)

• SMUX (using the SMUX library routines)

• distributed applications (including client/server applications)

• SMUX peers to communicate with SNMP agents (as part of a network management application)

• client programs that access the Network Information Service

• services that use the Service Access Protocol daemon to register themselves in the Server Information Table (in a NetWare or UnixWare^® network)

• applications consisting of multiple processes running on a single host that communicate using the same basic mechanism (UNIX domain sockets) that is available to distributed applications running on a network (Internet domain sockets)
