NonStop IPX/SPX Data Structures

Most data structures are common to the socket library and reside in the header files

subvolume $SYSTEM.ZTCPIP. Table 4-2 lists the NonStop IPX/SPX data structures,

and indicates the C header file in which each structure is declared and the type of call

that uses that structure.

For more information about the different types of socket library calls, see Section 5,

Library Routines; the socket function calls are listed in Table 5-1. The socket I/O

control operations are socket_ioctl and socket_ioctl_nw. The socket I/O

control operations and the structures they use are listed in Table 5-3.

In this section, the description of each structure includes the following information:

•

Purpose of the structure

•

Structure declaration

•

Description of each field in the structure declaration

•

Type of function call that uses the structure
