Summary: Does BSD use lockf()?

I have, for some time now, been using the library proceedure lockf() to do
my file locking and have found it a wonderful and elegant mechanism for doing
so (no, really :-)

However, I have only been doing this on SysV machines and now wonder how
portable my code will be to BSD UNIX.

Does BSD use the lockf() convention like SysV?  I've localized functions using
it in hopes that if it didn't I'd only have to fiddle with one area.  If it
doesn't, what does the file locking under BSD 4.3 look like?

PS.  If anyone has a Tandy 6000 (68000 based XENIX 3.1) I have an assembler
patch that fixes the _xlockin[g] dain-bramage in /lib/libc.a and would be happy
to mail it to you if you'd like (it's about 5 lines).

Jon
