This standard defines a set of system application program interfaces to operating system services. These interfaces provide access via the Ada programming language to the same operating system services for which C-language interfaces are specified in ISO/IEC 9945-1:1996 {2} 1)2)and IEEE P1003.1g {B14}.
The purpose of this standard is to support application portability at the Ada source code level. This standard is intended to be used by both application developers and system implementors.
This standard is intended to be compatible with implementations of the 1995 revision to the Ada language standard (ISO/IEC 8652:1995 {1}). Fall-back approaches compatible with implementations of the original Ada language standard (ISO/IEC 8652:1987 {B5}) are also provided (see 1.3).
This standard is intended to contain no specifications that conflict with “Year 2000” requirements.
This standard comprises three major components:
The following areas are outside the scope of this standard:
When the XTI Detailed Network Interface option and/or the Sockets Detailed Network Interface option are supported, then a set of DNI's (see 2.2.3.26) are also within the scope of this standard. A DNI is intended to provide access to protocol-specific features of the underlying network for highly portable applications that need access to sophisticated network features. The DNI's are based on the SPG4 XTI and 4.4 BSD socket specifications.
The following areas are outside of the scope of the DNI's:
This standard describes the external characteristics and facilities that are of importance to applications developers, rather than the implementation approaches that may be employed to achieve them. Special emphasis is placed on those facilities and capabilities needed for the broad spectrum of applications.
This standard has been defined exclusively at the source code level. The objective is that a Strictly Conforming POSIX.5 Application can be compiled to execute on any conforming implementation, within the portability of the application Ada code itself.

2) A language-independent definitions of this standard was once under development, but work on that project was suspended.
