Code:

char *img_basename(filename)

char *filename;

{

  char *new, *part;

  int len, dex;



  len = strlen(filename);  dex = len - 1;

  while (dex > -1) {

    if (filename[dex] == '/') {

      break;

    } else {

      dex--;

    }

  }

  dex++;

  part = &(filename[dex]);

  len = strlen(part);

  new = (char *) malloc ((unsigned) ((len + 1) * sizeof (char)));

  strcpy(new, part);

Re: wat is this function doing

It's getting the part of the filename that is beyond the '/', or the entire name if no '/' is present. Side note: don't waste your time putting "sizeof (char)" in a malloc. Unlike ints or other variables, sizeof char is ALWAYS 1.
