SOCKETS(POSIX) user functions

This chapter describes the SOCKETS(POSIX) interface functions for BS2000.

First, an overview of the function is given, grouped according to area of responsibility. Then all functions of the SOCKETS interface are described in alphabetical order. 

The functions for handling file descriptors are provided by the POSIX interface. The functions concerned are read(), readv(), write(), writev(), ioctl(), fcntl() and close() as well as poll() and select(). These functions are described in the manual "C Library Functions for POSIX Applications". Special features for using these functions with sockets are described at the end of this chapter under "Using standard POSIX functions for sockets".
