Callback Routines (advanced) in the CPLEX Callable Library (C API)

These callback routines are advanced. They are part of the legacy callback features prior to CPLEX V12.8.

Advanced routines typically demand a thorough understanding of the algorithms used by CPLEX. Thus they incur a higher risk of incorrect behavior in your application, behavior that can be difficult to debug. Therefore, the team encourages you to consider carefully whether you can accomplish the same task by means of other Callable Library routines instead.

For basic routines supporting callbacks, see also Callback Routines (basic) in the CPLEX Callable Library (C API).
