i cant make casting working...

      char dir_str[100];
dir_str[0] = '\0';
      strcat(dir_str, "/dev/");
      strcat(dir_str, (char*)utbufp->ut_line); // right here i get error mesg..

The code would not work even if i replace strcat(dir_str, (char*)utbufp->ut_line); with
strcat(dir_str, utbufp->ut_line);
Thanks in advance
