Socket Library Include Files

This chapter describes the socket library include files. It lists the structures and macro definitions included in each header file.

Overview

This chapter lists the include files used with the API socket library. These files define structures, macros, and constants referenced by the socket library and should be included during the compilation of any application programs that call socket library functions.

Socket library include files are installed on the local system as members of a partitioned data set. Include this data set in the SYSLIB DD concatenation when application programs are compiled. The data set name is determined during installation (default name T01TCP.H unless changed by the local system programmer). This table summarizes the contents of each include file:
