Yes, you could implement some subset : of POSIX in this environment, and even by fiddling, most : of it, but it is not clear that this is really worth while : if all you want is specific features (I must say I was : unaware of the POSIX standard including record locking, : but there is a lot of stuff there :-) I understand the 'POSIX subsystem' will be gone from NT 5.0 (or by whatever name). Not that anyone ever took it seriously. As far as POSIX goes, I am not really sure. The 1992 standard has, AFAIK, only file locking, not record locking. For some reason, I though the next standard would have record locking. But it is too expensive (as a interested individual) to stay current. In practice I have my own File_IO package which implements such items for the platforms I use myself.
