I'm writing some socket code, and I need to make sure that a final message
goes out before I disconnect. If I close the socket soon after writing
the message, it often doesn't make it out. Putting in a sleep(1) between
the write and the close fixes the problem, but since this one program
serves several sockets, I don't want to do that. Is there an equivalent
to fflush which works on sockets? My system has a man page for a routine
called flush, but it appears to be only for assembly language routines.

I haven't actually used it, but from my man pages, it looks like you can call setsockopt ( sock, SOL_SOCKET, SO_LINGER, optval, optlen); with optval a pointer to 'struct linger' (defined in <sys/socket.h>), and optlen set to its length. This is on SCO V.3.2. If this helps, maybe you can return a favour by casting an eye over my question in this group "HELP!! Sockets ..." (ian@hpopd.HP.COM) Cheers, Ian Watson
