Chapter Summary
In this chapter, we examined the functions provided to the programmer for controlling terminal input and output functions. Although these functions are not needed for basic terminal input and output, any program that requires special services such as input without echo or character-at-a-time input must make use of them. Because of the evolution of the terminal interface over the years, the functions described in this chapter are also one of the stickiest points in porting software between different versions of UNIX, and between other operating systems as well. However, the POSIX interface has gone a long way toward simplifying this interface and alleviating the portability problems.
