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 “Summary of POSIX/iX Library Functions” 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.
