Unfortunately, yes. But I recommend to wait for the new 1996 revision of POSIX (see below).
You can order the POSIX.1b standard (officially called IEEE Std 1003.1b-1993; this book includes also all text of POSIX.1 and costs 114 USD) as well as the other POSIX standards directly from IEEE:
phone: +1 908 981 1393 (TZ: eastern standard time) 1 800 678 4333 (from US+Canada only) fax: +1 908 981 9667 e-mail: stds.info@ieee.org
Information about POSIX and other IEEE standards is also available on <http://stdsbbs.ieee.org/>, however unfortunately the full standard documents are only available as books or on CD-ROM, not on the Internet. Having access to the POSIX specs is certainly a good idea for any Linux kernel hacker.
Here is a brief list of some of the POSIX standards:
POSIX.1 Basic OS interface (C language) POSIX.1a Misc. extensions (symlinks, etc.) POSIX.1b Real-time and I/O extensions (was: POSIX.4) POSIX.1c Threads (was: POSIX.4a) POSIX.1d More real-time extensions (was: POSIX.4b) POSIX.1e Security extensions, ACLs (was: POSIX.6) POSIX.1f Transparent network file access (was: POSIX.8) POSIX.1g Protocol independent communication, sockets (was: POSIX.12) POSIX.1i Technical corrections to POSIX.1b POSIX.2 Shell and common utility programs (date, ln, ...) POSIX.3 Test methods POSIX.5 ADA binding to POSIX.1 POSIX.7 System administration POSIX.9 FORTRAN-77 binding to POSIX.1 POSIX.15 Supercomputing extensions (checkpoint/recovery, etc.)
and a few others which are still in early draft stage. If you want to follow progress on POSIX standardization, you should follow the announcements in the moderated USENET group comp.std.unix.
ISO has also published POSIX.1 as ISO/IEC 9945-1:1990. ISO and IEEE will soon publish the new revision of this standard: ISO/IEC 9945-1:1996. This will be the new 1996 revision of POSIX.1 which will contain in one single standard POSIX.1(1990), POSIX.1b(1993), POSIX.1c(1995), and POSIX.1i(1995) (perhaps also POSIX.1a(1996) if it gets ready in time). If you want to order the POSIX standard but are not in a hurry, may be it is a good idea to wait a few months until ISO/IEC 9945-1:1996 is available. All differences between POSIX.1(1990) and POSIX.1(1996) will be marked by bars at the page margins.
