MPE/iX, Multiprogramming Executive with Integrated POSIX, is the latest
in a series of forward-compatible operating systems for the HP 3000
line of computers.
In HP documentation and in talking with HP 3000 users, you will encounter
references to MPE XL, the direct predecessor of MPE/iX. MPE/iX is
a superset of MPE XL. All programs written for MPE XL will run without
change under MPE/iX. You can continue to use MPE XL system documentation,
although it may not refer to features added to the operating system
to support POSIX (for example, hierarchical directories).
Finally, you may encounter references to MPE V, which is the operating
system for HP 3000s not based on PA-RISC architecture. MPE V software
can be run on the PA-RISC (Series 900) HP 3000s in what is known as
compatibility mode.
The Berkeley Sockets/iX Reference Manual is written for experienced
application programmers:
If you are an MPE/iX-based application programmer, you
may want to develop new applications for the HP 3000 that can be used
on other platforms as well.
If you are a UNIX-based application
programmer, you may want to port existing C-based applications to
the HP 3000 hardware platform.
This manual will assist application programmers in porting applications
from UNIX-based systems to MPE/iX-based systems.
The BSD sockets product was initially released on MPE/iX release 4.0. POSIX
functions were added for MPE/iX release 4.5. Additional socket functionality
has been added in release 5.0.
