how I get the font color of a word?

what I am doing wrong here?

I am trying to get the color of the word.

  PDWordFinderAcquireVisibleWordList(wordFinder, i, NULL, &wordInfo, &pXYSortTable, NULL, &numWords);

  for (ASInt32 k = 0; k<numWords;k++) {

       myWord = PDWordFinderGetNthWord(wordFinder, k);

       wordStyle = PDWordGetNthCharStyle(wordFinder, myWord, 0);

       if (wordStyle!=NULL){

            PDStyleGetColor(wordStyle, theColor);// I get an error here

       }

  }

the  guide says that I should use a pointer to the color structure but I cannot build the api if I use it this way.

      PDStyleGetColor(wordStyle, &theColor)

thanks in advance.
