XPRSaddcbchecktime

XPRSaddcbchecktime


Purpose
Declares a callback function which is called every time the Optimizer checks if the time limit has been reached. This callback function will be called in addition to any callbacks already added by XPRSaddcbchecktime.
Synopsis
int XPRS_CC XPRSaddcbchecktime(XPRSprob prob, int (XPRS_CC *f_checktime)(XPRSprob my_prob, void* my_object), void* object, int priority);
Arguments
prob 
The current problem.
f_checktime 
The callback function which takes two arguments, my_prob and my_object, and has an integer return value. This function is called every time the Optimizer checks against the time limit.
my_prob 
The problem passed to the callback function, f_checktime.
my_object 
The user-defined object passed as object when setting up the callback with XPRSaddcbchecktime.
object 
A user-defined object to be passed to the callback function, f_checktime.
priority 
An integer that determines the order in which multiple checktime callbacks will be invoked. The callback added with a higher priority will be called before a callback with a lower priority. Set to 0 if not required.
Further information
If the callback function returns a nonzero value the solution process will be interrupted.
