How to Use This Manual
This manual is intended to be used with the following four manuals:
* HP C/iX Library Reference Manual (30026-90001)
* MPE/iX Developer's Kit Reference Manual Volume 2 (36430-90002)
* MPE/iX Shell and Utilities Reference Manual, Volumes 1 and 2
(36431-60001)
* The POSIX.1 Standard - A Programmer's Guide (36430-90003)
This manual describes C library functions defined by the POSIX.1
standard. Additional C library functions available through the POSIX/iX
library are documented in the HP C/iX Library Reference Manual
(30026-90001).
Using the HP C/iX Library Reference Manual
The HP C/iX Library Reference Manual (30026-90001) contains reference
descriptions of ANSI C library functions that are required by the POSIX.1
standard. Some of the functions in the HP C/iX Library Reference Manual
(30026-90001):
* Do not correctly describe the POSIX/iX function. Refer to this
manual, the MPE/iX Developer's Kit Reference Manual Volume 1
(36430-90001) for the appropriate descriptions. The following is
a list of those functions:
* access()
* close()
* creat()
* dup()
* getenv()
* getopt()
* getpid()
* isatty()
* lseek()
* open()
* read()
* sleep()
* system()
* time()
* write()
* Are not implemented in the POSIX/iX library. At this time there
is only one function that is not implemented:
* link()
* Support the HP C/iX compiler product and do not apply to the
MPE/iX product. Table 1-1 lists the POSIX/iX functions, which
functions are implemented in POSIX/iX, and where you can find the
POSIX/iX function description.
The POSIX.1 standard requires that certain ANSI C library functions have
additional capabilities or characteristics. These extensions to the
behavior of ANSI C library functions are described in the HP C/iX Library
Reference Manual (30026-90001) under the appropriate function
description. This manual is available as a special core supplement to
the MPE/iX FOS manual set.
Using the MPE/iX Developer's Kit Reference Manual, Volume 2
The MPE/iX Developer's Kit Reference Manual Volume 2 (36430-90002)
contains descriptions of C library functions available through additional
relocatable libraries provided with the MPE/iX Developer's Kit. Refer to
the MPE/iX Developer's Kit Reference Manual Volume 2 (36430-90002) for
more information.
Using the MPE/iX Shell and Utilities Reference Manual
The MPE/iX Shell and Utilities Reference Manual, Volumes 1 and 2
(36431-60001) provide descriptions of shell commands, headers, and
utilities defined in the POSIX.1 standard or in Appendix B of IEEE
P1003.2/D11.2. For more information about this, refer to the MPE/iX
Shell and Utilities Reference Manual, Volumes 1 and 2 (36431-60001).
This manual set is available as part of the Developer's Kit.
Using The POSIX.1 Standard - A Programmer's Guide
The POSIX.1 Standard - A Programmer's Guide (36430-90003) provides
additional information on the POSIX.1 standard and POSIX.1 application
programming.
The POSIX.1 Standard - A Programmer's Guide (36430-90003) is written to
describe how to program in a strictly conforming POSIX.1 environment.
You should understand all implementation considerations associated with
the POSIX/iX library before using The POSIX.1 Standard - A Programmer's
Guide (36430-90003) as a programming aid for application development on
MPE/iX.
