In article <7997@cbnews.ATT.COM> mark@cbnews.ATT.COM (Mark Horton) writes: >Is this something that should be fixed in the ANSI C standard? No -- The Standard doesn't create the problem, it merely documents it. There is no prohibition against C implementations doing a better job than the minimum guaranteed by the C Standard. In fact the C Standard guarantees very little about signal behavior, because of the wide variety of signal() implementations in existence. Remember that the C Standard is not UNIX specific, but rather applies to all operating systems. IEEE Std 1003.1 (POSIX) provides specifications for a much more reliable signal mechanism. Presumably UNIX-like implementations will provide the extended POSIX signal support rather than merely a minimal ANSI C facility for signals.
