Examples

This code gets the value of a shared variable of type integer:

curGroup = session -> GetCurrGroup();
fid = session -> GetSharedVarID(curGroup, "i_svar");
if (fid == 0xffff) 
{
   MessageBox(NULL, "Illegal fid!", "default", MB_OK);
   return;
}
i_val = session-> GetIntSharedVar(curGroup, fid, 
   isNull);
session-> SetIntSharedVar(curGroup, fid, i_val+1);
