I disagree with the design standards and the very concept of a number of RT tools and I am not thrilled about PS/2 AIX being made compatible with RT on that level. I do not recall if this was even mentioned in the same article, but it definitely was not mentioned in the same thought-thread, which dealt with RT's and PS2's BSD-feel as is exemplified by process/job control. >POSIX 1003.1 compliance involves supporting a BSD-like signalling >mechanism, a SysV-like terminal IO subsystem, and a number of >special-purpose functions instead of ioctls with varying numbers and >types of arguments, which were difficult or impossible to rationalize >with ANSI C. That's been done in AIX/370. The compilers (386 and 370) support ANSI C, but the system was written in the "standard" K&R C, just like sVr2 and BSD 4.3. -- "No regrets, no apologies" Ronald Reagan Oleg Kiselev ARPA: lcc.oleg@seas.ucla.edu, oleg@gryphon.COM (213)337-5230 UUCP: [world]!{ucla-se|gryphon}!lcc!oleg
