NAME
       tapset::tcp - systemtap tcp probe points



DESCRIPTION
       This family of probe points is used to probe TCP layer activities.  It contains the following probe points:


       tcp.sendmsg

              Fires whenever sending a tcp message

              Arguments:

              sock
                network socket

              size
                number of bytes to send


       tcp.sendmsg.return

              Fires whenever sending message is done

              Arguments:

              size
                number of bytes sent


       tcp.recvmsg

              Fires whenever a message is received

              Arguments:

              sock
                network socket

              size
                number of bytes to be received


       tcp.recvmsg.return

              Fires whenever message receiving is done

              Arguments:

              size
                number of bytes received


       tcp.disconnect

              Fires whenever tcp is disconnected

              Arguments:

              sock
                network socket

              flags
                TCP flags (e.g. FIN, etc)


       tcp.disconnect.return

              Fires when returning from tcp.disconnect

              Arguments:

              ret
                error code (0: no error)
