This is plain nonsense. read in Linux (or anywhere else) CANNOT be ANSI compliant for the simple reason that the ANSI/ISO C standard does NOT define such a function. read may (or may not) be POSIX, SVID or XPG compliant. >Anyway, can someone who really knows the score here tell us: > >Which of Unix, Posix, Spec 1170, X/Open have approved national and/or >international standards. For an operating system to be allowed to be officially named UNIX(TM) it has to be validated by X/Open, the current owner of the UNIX brand. This validation is based on compliance to XPG 4.2. I don't know the details. Dan -- Dan Pop CERN, CN Division Email: danpop@mail.cern.ch Mail: CERN - PPE, Bat. 31 R-004, CH-1211 Geneve 23, Switzerland
