Very Computer

Hi All,
                I am working on a TALK implementation and everything
seems to be working perfectly except for the termination part.  
I want to how i can send Ctrl-C to the client on the other
machine so that i can terminate his process as well as mine.  
Please suggest me a way to send the signals
from one machine to the other over the socket connection.  

Thanks in advance
Ganesh

If you just close the socket, the other end will get SIGPIPE when it
tries to write to it.

Here's the routine I used to do it in a telnetd.  It only sends one byte as
urgent data since there's a discrepency between the spec and some implementations
as to whether the tcp urgent pointer points at the urgent data or just past it.
This work around made that a bit moot.

inline int telnet_state::write_oob(int fd,unsigned char *outbuf,size_t numchars)
{
    int retval,n=0;

    if (numchars > 1) {
        // send URGENT all by itself
        n+= send(fd,(const char*) outbuf, numchars-1, 0);
    }
    if(numchars > 0){
        retval= send(fd,(const char*)( outbuf+n-1), 1, MSG_OOB); /*URGENT data*/
        if(retval>0){
            n+=retval;
        }
    }
    return n;

If you manage to get this working, please let me know.  There's a few
processes on your machine I'd like to send arbitary singals to...
