Any pointers for using this function? When I try: fp = (FILE *)plLibOpenPdfstrm(filename); instead of: fp = fopen(filename, "r"); I get a segmentation fault at my first attempt to read from the file: fscanf(fp, "%d\n", &number_colors); My guess was that this was due to the fact that it opens the file in "rb" mode instead of "r" mode, but when I modified it to use "r" mode I still got the same segfault. -Hazen ------------------------------------------------------------------------------ Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!
