# include/wait_for_binlog_checkpoint.inc
#
# SUMMARY
#
# Wait until binlog checkpoint has been logged for current binlog file.
# This is useful to avoid races with output difference for binlog
# checkpoints, as these are logged asynchronously from the binlog
# background thread.
#
# USAGE:
#
# --source include/wait_for_binlog_checkpoint.inc
