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.
