Call the
PowerBuilder function

Before you call the function, you must supply the integers to be
multiplied. For the sake of simplicity, the following code sets them
directly in the PBCallInfo structure.

   // Set IN arguments. The prototype of the function is
   // integer f_mult(integer arg1, integer arg2)
   ci.pArgs-&gt; GetAt(0)-&gt;SetInt(123);
   ci.pArgs-&gt; GetAt(1)-&gt;SetInt(45);

// Set IN arguments. The prototype of the function is

// integer f_mult(integer arg1, integer arg2)

ci.pArgs-> GetAt(0)->SetInt(123);

ci.pArgs-> GetAt(1)->SetInt(45);

Finally call the function, wrapping it in a try-catch statement
to handle any runtime errors:

   // Call the function
   try
   {
      session-&gt;InvokeObjectFunction(pbobj, mid, &amp;ci);

      // Was PB exception thrown?
      if (session-&gt;HasExceptionThrown())
      {
         // Handle PB exception
         session-&gt;ClearException();
      }
   }
   catch (...)
   {
      // Handle C++ exception
   }

   // Get the return value and print it to the console
   pbint ret = ci.returnValue-&gt;GetInt();
   fprintf(stderr, "The product of 123 and 45 is %i
",
      ret);

// Call the function

try

{

session->InvokeObjectFunction(pbobj, mid, &ci);

// Was PB exception thrown?

if (session->HasExceptionThrown())

{

// Handle PB exception

session->ClearException();

}

catch (...)

{

// Handle C++ exception

}

// Get the return value and print it to the console

pbint ret = ci.returnValue->GetInt();

fprintf(stderr, "The product of 123 and 45 is %i

ret);
