INDEX

ILOG CPLEX detects many different kinds of errors and generates exception, warnings, or error messages about them.

To query exceptions in Concert Technology, use the methods:

IloInt IloCplex::Exception::getStatus() const;

const char* IloException::getMessage() const;

To view warnings and error messages in the Callable Library, you must direct them either to your screen or to a log file.

To direct all messages to your screen, use the routine CPXsetintparam to set the parameter CPX_PARAM_SCRIND.
To direct all messages to a log file, use the routine CPXsetlogfile.
