10.2.4 Signals supported by Linux
Linux supports nearly every signal provided by SVR4, BSD, and POSIX, with few exceptions:
- SIGEMT is not supported; it corresponds to a hardware fault under SVR4 and BSD.
- SIGINFO is not supported; it is used for keyboard information requests under SVR4.
- SIGSYS is not supported; it refers to an invalid system call in SVR4 and BSD. If you link with libbsd, this signal is redefined to SIGUNUSED.
- SIGABRT and SIGIOT are identical.
- SIGIO, SIGPOLL, and SIGURG are identical.
- SIGBUS is defined as SIGUNUSED. Technically there is no ``bus error'' in the Linux environment.
