? From: Chris Torek <chris at mimsy.umd.edu>
? bob at omni.com (Bob Weissman) asks why there is an `#ifdef vax' around the
? `char *sprintf()' declaration in stdio.h.
? The reason is that sprintf() is supposed to return an int value, namely
? the number of characters printed, but it was `too painful' to fix this for
? 4.2 and 4.3 BSD, so it was left *wrong* in the BSD VAX systems and made
? correct in SunOS.
Made correct in which version? I ran a test prog under 3.5 and it returns
the first arg. My Version 4 (probably 4.0) manual sez that it still
returns char *. I have no access to a running 4.x system.
? Why the `#ifdef vax' ... `#endif' lines were never removed from the Sun
? stdio.h I cannot answer. Note that sprintf() has been fixed in
? 4.3BSD-tahoe.
Perhaps your local SunOS/BSD hybrid has the Tahoe sprintf?
