• shutdown SOCKET,HOW

  Shuts down a socket connection in the manner indicated by HOW, whichhas the same interpretation as in the syscall of the same name.

   shutdown(SOCKET, 0); # I/we have stopped reading data
   
   shutdown(SOCKET, 1); # I/we have stopped writing data
   
   shutdown(SOCKET, 2); # I/we have stopped using this socket
   

  This is useful with sockets when you want to tell the otherside you're done writing but not done reading, or vice versa.It's also a more insistent form of close because it alsodisables the file descriptor in any forked copies in otherprocesses.

  Returns 1 for success; on error, returns undef ifthe first argument is not a valid filehandle, or returns 0 and sets$! for any other failure.
