Purpose
Returns the primal values from the solution associated with the current callback.
Topic areas
Solution, Callback
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.

Example

Further information
1. The function always returns data in the input space, even if the problem is currently in presolved state. Column indices should be in the range 0 to INPUTCOLS- 1.
2. This function may only be called within the following callbacks:

Callback | Solution type returned
--- | ---
bariteration | Barrier iteration solution
chgbranchobject | Node relaxation solution
cutround | Node relaxation solution
intsol | New incumbent solution
nodelpsolved | Node relaxation solution
optnode | Node relaxation solution
preintsol | Candidate incumbent solution
slpcascadeend | SLP iteration solution
slpcascadestart | SLP iteration solution
slpintsol | New incumbent solution
slpiterend | SLP iteration solution
