Closing Log Files

INDEX

If you do not want ILOG CPLEX to record messages in a log file, then you can close the log file from the Interactive Optimizer with the command set logfile *.
By default, routines from the Callable Library do not write to a log file. However, if you want to close a log file that you created by a call to CPXsetlogfile, call CPXsetlogfile again, and this time, pass a NULL pointer as its second argument.
From Concert, use the setOut method with env.getNullStream as argument, where env is an IloEnv object, to stop sending logging output to an output stream.
