- Patch #1 for "tt" - Tetris for terminals
- ========================================
-
- This is not a bug-fix as such, but a short piece of code to be
- appended to the header-file tt.h, which will allow tt to run on
- Berkeley UNIXes older than 4.3, (ie. those without the FD_ macros).
- These macros were introduced in 4.3 (and in SunOS 4.0) since these
- UNIXes allow more than 32 file-descriptors open at once, and thus they
- can no longer all be flagged by setting bits in a 32-bit long integer.
-
- In fact, "tt" only select()s on one file-descriptor at a time, so the
- lack of width will certainly be no problem. The macros as defined
- here simply twiddle the bits of a long integer in much the same way as
- I would have done in the first place had I written "tt" to run under
- 4.2, but using the same names as the corresponding 4.3 macros, so none
- of the existing "tt" code need be changed.
-
- Sorry I didn't think of this before I posted the first time!
