This is an advanced routine. Advanced routines typically demand a profound understanding of the algorithms used by ILOG CPLEX. Thus they incur a higher risk of incorrect behavior in your application, behavior that can be difficult to debug. Therefore, ILOG encourages you to consider carefully whether you can accomplish the same task by means of other Callable Library routines instead.
The routine CPXgetsolvecallbackfunc accesses the
user-written callback to be called during MIP optimization to optimize the
subproblem.
Example
CPXgetsolvecallbackfunc(env, ¤t_callback, ¤t_cbdata);
See also Advanced MIP Control Interface in the ILOG CPLEX User's Manual.
For documentation of callback arguments, see the routine CPXsetsolvecallbackfunc.
Parameters
env
A pointer to the CPLEX environment,
as returned by CPXopenCPLEX.
solvecallback_p
The address of the pointer to the current user-written solve callback. If no callback has been set, the pointer evaluates to NULL.
cbhandle_p
The address of a variable to hold the user's private pointer.
