int
stripfilenameandpath (char *path, char *onlypath, char *onlyfilename)
{
/*
documentacao

path = path com path e arquivo
onlypath = somente o path
onlyfilename = somente o arquivo sem o path

*/
    int ret;
    int i;
    int p;
    char temp[255];

    char *fixo;
#ifdef WIN32
    const int separator = '\\';
#else
    const int separator = '/';
#endif

    fixo = path;

    if (path == NULL)
      {

          if (onlypath != NULL)
            {
                memset (onlypath, 0, 1);
            }

          if (onlyfilename != NULL)
            {
                memset (onlyfilename, 0, 1);
            }

          return 1;
      }

    ret = strlen (path);

    if (!ret)
      {

          if (onlypath != NULL)
            {
                memset (onlypath, 0, 1);
            }

          if (onlyfilename != NULL)
            {
                memset (onlyfilename, 0, 1);
            }

          return 0;
      }

    for (i = 0; i  -1; i--)
      {

          if (temp[i] == separator)
            {
                temp[i + 1] = 0;
                break;
            }
          p++;
      }

    p = ret - p;

    fixo += p + 1;

    if (onlypath != NULL)
      {
          strcpy (onlypath, temp);
      }

    if (onlyfilename != NULL)
      {
          strcpy (onlyfilename, fixo);
      }

    return 0;
}
