10.2.4 Signals supported by Linux

Next: 10.3 Terminal I/O Up: 10.2 Signal handling Previous: 10.2.3 signal under 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.
