Synopsis
int XPRS_CC XPRSaddcbchecktime(XPRSprob prob, int (XPRS_CC *checktime)(XPRSprob cbprob, void* cbdata), void* data, int priority);
Arguments
prob 
The current problem.
checktime 
The callback function which takes two arguments, cbprob and cbdata, and has an integer return value. This function is called every time the Optimizer checks against the time limit.
cbprob 
The problem passed to the callback function, checktime.
cbdata 
The user-defined data passed as data when setting up the callback with XPRSaddcbchecktime.
data 
A user-defined data to be passed to the callback function, 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. If multiple callbacks of this type are registered, then all of them will be invoked and the solution process will be interrupted if any of them returned a nonzero value.
