Implementations may support additional si_code values not included in this list, may generate values
included in this list under circumstances other than those described in this list, and may contain exten-
sions or limitations that prevent some values from being generated. Implementations will not generate a
different value from the ones described in this list for circumstances described in this list.
In addition, the following signal-specific information will be available:
Signal Member Value
SIGILL void * si_addr address of faulting instruction
SIGFP
SIGSEGV void * si_addr address of faulting memory reference
SIGBUS
SIGCHLD pid_t si_pid child process ID
int si_status exit value or signal
real user ID of the process that sent
the signal
uid_t si_uid
band event for
POLL_IN,
POLL_OUT,orPOLL_MSG
SIGPOLL long si_band
For some implementations, the value of si_addr may be inaccurate.
