Hi there,

I developed a program in C/C++ that use CPLEX to solve several Linear Programming problems.
I would like to know how much time CPLEX is spending on the presolve without letting CPLEX to print the information on the screen.

Does anybody know how can I get the presolve time?

Regards,
Vitor

Please try like this: 
status = CPXgettime (env, &t1);
status = CPXpresolve (env, lp, CPX_ALG_DUAL);
status = CPXgettime (env, &t2);
printf("presolve time: %f\n", t2 - t1);
