| 38 | ?S: which indicates if your fd_set typedef contains the fds_bits member. | |
| 39 | ?S: If you have an fd_set typedef, but the dweebs who installed it did | |
| 40 | ?S: a half-fast job and neglected to provide the macros to manipulate | |
| 41 | ?S: an fd_set, HAS_FDS_BITS will let us know how to fix the gaffe. | |
