Chapter 6 Migrating C Programs to HP-UX This chapter discusses issues to consider when migrating C language programs from VAX systems, HP 9000 Series 300/400, and HP 9000 Series 500 computers to HP 9000 Series 700/800 computers. The first section lists some steps you need to take to migrate an application program to an HP 9000 Series 700/800 computer. Subsequent sections in this chapter highlight major differences between various C compilers and suggest how to modify source files to ease migration. Because C is a highly portable language, if you follow the recommendations given in the chapter "Programming for Portability," your program should migrate easily. However, if you use system-dependent programming practices, a program that executes successfully on one computer may not execute properly when transferred to a HP 9000 Series 700/800 computer. For example, if you use system-specific I/O routines outside of the standard C library, you will have difficulty with portability.
