I'm not much of a System V user, and I've always been lazy and fooled
with compatibility libs on most SVR[34] machines (I know I know, for
shame) to get bzero, bcopy and bcmp functionality. Anyway, now I have
to build BSD telnetd for a Sequent running DYNIX/ptx 2.1.0 and lo, it's
just SVR3(?) no compatibility anything. So anyway, for example, we
have a bcopy in slc.c:
/*
* save this slc buffer if it is the first, otherwise dump
* it.
*/
if (def_slcbuf == (unsigned char *)0) {
def_slclen = len;
def_slcbuf = (unsigned char *)malloc((unsigned)len);
if (def_slcbuf == (unsigned char *)0)
return; /* too bad */
bcopy(ptr, def_slcbuf, len);
}
What should that bcopy() look like to make this SVR3 system happy?
Is there a "right" way to implement bcopy() etc on this system so I could
generate my own compatibility library and not bother with altering the
code every time?
Working with gcc 2.6.2 if it matters.
