The following documentation is available to familiarize the user and to facilitate working with the POSIX subsystem in BS2000:
An introduction to working with the POSIX subsystem is presented in the manual "POSIX - Basics for Users and System Administrators" [1 (Related publications)]. Furthermore, the administration tasks that arise in conjunction with the POSIX subsystem are described. You also learn with which BS2000/OSD software products you can use the POSIX subsystem.
A comprehensive description of the POSIX commands that can be used when working in the POSIX shell can be found in the manual "POSIX - Commands".
The "POSIX Commands of the C and C++ Compilers" manual [5 (Related publications)] provides an introduction to the C-/C++ programming environment in the POSIX shell environment, describes how to compile and link C and C++ programs with the POSIX commands cc, c89 and CC and shows you how to control the global C and C++ list generator with the POSIX command ccxref.
The "POSIX V1.1A Sockets/XTI for POSIX" manual is intended for C and C++ programmers that develop communication applications with SOCKETS or XTI functions based on the POSIX interface.
"NFS V3.0 / NFS V1.2C Network File System"
POSIX documentation in the BS2000/OSD environment
Many software products in BS2000 have been functionally extended to include the POSIX functionality.
A number of utility routines provide access to the POSIX file system. The file editor EDT, for example, can also process files of the POSIX file system.
Due to the CRTE (Common Runtime Environment) extensions based on the XPG4 standard, it is possible to write portable C programs using the C library functions independently of the executing operating system.
Familiarity with the manual "POSIX - Basics for Users and System Administrators" is essential as a foundation for accessing POSIX functionality from other software products.
