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 workstations and servers.
The first section lists some steps you need to take to migrate an
application program to an HP 9000 workstation or server. 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
workstation or server. For example, if you use system-specific I/O
routines outside of the standard C library, you will have difficulty
with portability.
