Synopsis
int XPRS_CC XPRSgetcallbacksolution(XPRSprob prob, int *p_available, double x[], int first, int last);
Arguments
prob 
The current problem.
p_available 
This variable will be set to 1 if a solution is available. May be NULL if not required.
x 
Double array of length last-first+1 where the values of the primal variables will be returned. May be NULL if not required.
first 
First column in the solution to return.
last 
Last column in the solution to return.
