How CPLEX works

CPLEX carries out these activities when it is invoked from the Callable Library (C API).

Overview
Your C code includes these basic steps in a Callable Library application.
Opening the CPLEX environment
Your Callable Library application initializes the CPLEX environment.
Instantiating the problem object
Your Callable Library application creates a problem object in the environment.
Populating the problem object
Your Callable Library application populates the problem object with data.
Changing the problem object
If your Callable Library application modifies the problem object, consider these issues.
