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