signal(5) signal(5)
SI_ASYNCIO The signal was generated by the completion of an asynchronous I/O
request.
SI_MESGQ The signal was generated by the arrival of a message on an empty message
queue.
If the signal was not generated by one of the functions or events listed above, the si_code will be set to an
implementation-defined value (see below) that is not equal to any of the values defined above.
If si_code is one of SI_QUEUE, SI_TIMER, SI_ASYNCIO,orSI_MESGQ, then si_value will contain the
application-specified signal value. Otherwise, the contents of si_value are undefined.
The macros specified in the Code column of the following table are defined for use as values of si_code that
are signal-specific reasons why the signal was generated.
Signal Code Reason
SIGILL ILL_ILLOPC illegal opcode
ILL_ILLOPN illegal operand
ILL_ILLADR illegal addressing mode
ILL_ILLTRP illegal trap

SIGCHLD CLD_EXITED child has exited
CLD_KILLED child has terminated abnormally and
did not create a core file
CLD_DUMPED child has terminated and created a core file
CLD_KILLED child was killed
CLD_DUMPED child has terminated abnormally
CLD_TRAPPED traced child has trapped
CLD_STOPPED child has stopped

POLL_PRI high priority input available
POLL_HUP device disconnected
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 extensions
or limitations that prevent some values from being generated. Implementations will not generate a
