ERRORS
       EBADF  fd is not a valid file descriptor or is not open
              for writing.

       EPIPE  fd is connected to a pipe or socket whose reading
              end is closed.  When this happens the writing pro­
              cess  will receive a SIGPIPE signal; if it catches,
              blocks or ignores this the error EPIPE is returned.
                                             
                                             
 Ja myslim, ze je to jasne. Jste si jist, ze ten socket nikdy nebyl
 zivy a ze nepisete do mrtveho socketu coz je neco jineho nez
 neinicializovany? :-)
