Get the size of an array of variables.

Size (= number of variables) of the array, or -1 in case of an error.

XPRBprob prob;
XPRBarrvar ty1;
int tsize;
   ...
ty1 = XPRBnewarrvar(prob, 10, XPRB_PL, "arry1", 0, 500);
tsize = XPRBgetarrvarsize(ty1);

This gets the size of the array ty1.

This function returns the size ( i.e. the number of elements) of an array of variables. If the variables have been added incrementally the returned value may be smaller than the maximum size given at the creation of the array. The returned size represents the number of variables that have actually been added to the array.
