Examples

This example uses TutSetFileCloseFunc to perform post-processing on a data file:

static T_PTR find_name(t_file, arg) 
T_FILE t_file; 
T_PTR arg; 
{ 
 
  if (t_file->file == (FILE *)arg) { 
    return t_file->fname; 
  } 
 
  return NULL; 
 
} /* find_name */ 
 
static T_BOOL close_func(file) 
FILE *file; 
{ 
  T_STR fname; 
 
  fname = TutFileTraverse(find_name, file); 
  if (fname == NULL) { 
    /* error */ 
  } 
  fclose(file); 
  TutOut("Closing file %s\n", fname); 
  postprocess_file(fname);   /* user provided function */ 
   
}
