| | | | | | value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future.

| | | | | | | unmaintainable). these days, people use source. these id's do not provide any benefit, and do hurt the small install media (the 33,000 line diff is essentially mechanical) ok with the idea millert, ok dms

* warnx?/errx? paranoia (use "%s" not a bare string unless it is amillert2000-06-301-4/+4
| | | | | | | | | constant). These are not security holes but it is worth fixing them anyway both for robustness and so folks looking for examples in the tree are not misled into doing something potentially dangerous. Furthermore, it is a bad idea to assume that pathnames will not include '%' in them and that error routines don't return strings with '%' in them (especially in light of the possibility of locales).
* Don't bother calling nl() in init_display, just do the '\r' -> '\n' conversionmillert1999-03-231-3/+2
| | | | | | ourselves in display(). Since we don't use the curses input routines we have to do the conversion by hand. This is cheap because input processing is done on a per-character basis. Closes PR 783.
* Use cbreak(), not crmode() since crmode is just #define'd to cbreakmillert1999-03-231-3/+4
| | | | | | | anyway. Add a call to nl() after the cbreak(). This would fix PR #783 except that ncurses does not set ICRNL/ONLCR in nl() like I think it should. PR #783 will be fixed once that issue is resolved so consider this part one of two...
