#  export_scnl configuration file
#
#  Exports messages from a given list of station/comp/network/loc codes
#
#Background:  
# Import/Export are the long-distance message transfer
# modules. They operate as one-on-one pairs. There are two variants of
# export: export_generic, which ships messages with specified logos, and
# export_scnl which ships only trace data, but with specified SCNL names.
#
# Import/Export send heartbeats to each other, as well as into their
# local earthworm systems. If the heartbeat from the distant partner is
# not received whithin the expected time period (RcvAliveInt) the link is
# terminated, and an attempt to reconnect is initiated. If things go
# seriously wrong, the heartbeat into the local earthworm system in
# stopped. The expectation is that "restartMe" has been set in the .desc
# file, and we'll be killed and restarted.
#
# All socket operations are performed with a timeout. This is noramlly
# defaulted, but can be set in this file (SocketTimeout).
#
# Export maintains a circular FIFO buffer of messages to be shipped. The
# size of this buffer (RingSize) controls the maximum latency of the
# data.
#
#
#Configuration notes:
#
# "restartMe" should be stated in our desc file.
#
# The period of our local heartbeat (HeartBeatInt) must be safely smaller
# (faster) than our advertised period in our .desc file (tsec:).
# Otherwise we'll get continually restarted for no good reason.
# Note that tsec:0 implies no heartbeats expected, and so we'll never get
# restarted.
#
# The rate at which we send heartbeats to our distant partner should be
# considerably faster than the rate at which our partner expects them.
# Otherwise, a heartbeat delayed in transmission will cause our partner to
# conclude that the link is broken, and cause them to break the link and
# reinitialize. Which will cause us to do the same.
#
# For export, the ServerIPAdr is  the address of the port to be used in
# the exporting machine.  This is to specify a network card case the
# exporting machine has several network cards.
#
# If SocketTimeout is specified, it should be at least as large as the
# expected period of heartbeats from our distant partner.

# Socket commands (optional)
#---------------------------
# SocketTimeout defaults to RcvAliveInt + 3
#  If set to -1, all socket calls will block (no timeout).
#  SocketTimeout has no effect in export, unless it is set to -1,
#  because there is no code in export to handle socket timeouts.
#  If set to -1, the program may run slightly more efficiently because
#  timeout checking code will not execute.
#
#SocketTimeout 200000  # Timeout length in milliseconds for socket calls

#SocketDebug   0       # if 1, socket_ew debug statements are logged
                       # if 0, socket_ew debug is turned off (default)

# NOTE: Send_scn and Send_scn_remap commands are now obsolete, and 
# have been replaced with Send_scnl and Send_scnl_remap (which 
# include the location code field).  If the old commands are used, 
# export_scn sets the location code field to * (wildcard).
#
# Use any combination of Send_scnl (to send data as-is) and 
#   Send_scnl_remap (to change the SCNL on the fly) commands.
# Use * as a wildcard for any field. A wildcard in the
#   "map to" fields of Send_scnl_remap means that field will
#   not be renamed.
