Synopsis
int XPRBgetindicator(XPRBctr ctr);
Argument

Return value
0 
an ordinary constraint;
1 
an indicator constraint with condition b=1;
-1 
an indicator constraint with condition b=0;
-2 
an error has occurred.
Example 
XPRBprob prob;
XPRBctr ctr1;
int istat;
   ...
ctr1 = XPRBnewctr(prob, "r1", XPRB_L);
istat = XPRBgetindicator(ctr1);
This determines whether ctr1 is an ordinary constraint or an indicator constraint.
