[net.unix] ftruncate on SYS V ???

geo@necis.UUCP (George Aguiar ext. 224) (01/09/86)

Is it possible to truncate a file knowing only the file descriptor???
I am porting dmail to SYSTEM V on a 68000 machine and this one has me
stumped. dmail uses the ftruncate(2) system call which is not included
with SYS V. Please e-mail.

thanks,
