48

49

50
|                                  specific parameters.
51
|                       copy_arg : duplicate the structure created by
52
|                                  make_arg
53
|                       free_arg : Release the memory allocated by make_arg
54
|                                  or copy_arg
55
|
56
|                    At least make_arg must be non-NULL.
57
|                    You may pass NULL for copy_arg and free_arg if your
58
|                    make_arg function doesn't allocate memory and your
59
|                    arg fits into the storage for a (void*).

62
