IltmmConvert::get_SourceProgramCount Example for C++

This example will select the last program of a multi-program file. There is no error checking to make the example easier to understand.

void SelectLastProgram(IltmmConvert *pConvert) 
{ 
   long SourceProgramCount = 0; 
   pConvert->get_SourceProgramCount(&SourceProgramCount); 
   if(SourceProgramCount > 1) 
   { 
      /* If there is more than one program, select the last program. If there is only one program, you are already on the last program. The program index is 0-based, so the allowed value to pass to IltmmConvert::put_CurrentSourceProgram is between 0 and SourceProgramCount - 1 */ 
      pConvert->put_CurrentSourceProgram(SourceProgramCount - 1); 
   } 
}
