ISO/IEC POSIX.1-1990 from the IEEE

On September 28, 1990, the IEEE Standards Board formally approved IEEE Std
1003.1-1990: IEEE Standard for Information Technology  Portable Operating
System Interface (POSIX)  Part 1: System Application Program Interface (API)
[C Language].  Because IEEE Std 1003.1 is identical to the 1990 version of
ISO/IEC 9945-1, the IEEE standard will be published and distributed as the
international standard ISO/IEC 9945-1 : 1990 (IEEE Std 1003.1-1990).  This
standard is a revision of IEEE Std 1003.1-1988.

Abbreviated as POSIX.1, the standard defines a standard operating system
interface and environment for supporting application portability at the
source-code level in a UNIXr-based environment.  POSIX.1 describes external
characteristics, functions, and facilities of importance to application
developers, emphasizing those services required to effectively process an
array of commercial applications.

The standard contains terminology, concepts, and specifications governing
structures, headers, environment conditions, and related requirements. It
defines system service interfaces and subroutines, language-specific services
for C, and addresses portability, error handling, and error recovery issues.

Future IEEE publications within the POSIX family of standards are currently
under consideration, including: Shell and Utility Facilities; C, Ada, and
FORTRAN Bindings; Networking Protocols; Real-time Extensions; and Verification
Testing.

The POSIX standard will NOT be available in electronic format. It is
available now, in published form only, at a list price of $75.00 plus shipping
and handling.  To order by phone, call 1 (800) 678-IEEE in the continental US
8am - 4pm (EST).  Outside the US and Canada, please call (908) 981-1393.
