ENUM UTRACE_SIGNAL_A(9) utrace core API ENUM UTRACE_SIGNAL_A(9)NAME
enum_utrace_signal_action - disposition of signal
SYNOPSIS
enum utrace_signal_action {
UTRACE_SIGNAL_DELIVER,
UTRACE_SIGNAL_IGN,
UTRACE_SIGNAL_TERM,
UTRACE_SIGNAL_CORE,
UTRACE_SIGNAL_STOP,
UTRACE_SIGNAL_TSTP,
UTRACE_SIGNAL_REPORT,
UTRACE_SIGNAL_HANDLER
};
CONSTANTS
UTRACE_SIGNAL_DELIVER
Deliver according to sigaction.
UTRACE_SIGNAL_IGN
Ignore the signal.
UTRACE_SIGNAL_TERM
Terminate the process.
UTRACE_SIGNAL_CORE
Terminate with core dump.
UTRACE_SIGNAL_STOP
Deliver as absolute stop.
UTRACE_SIGNAL_TSTP
Deliver as job control stop.
UTRACE_SIGNAL_REPORT
Reporting before pending signals.
UTRACE_SIGNAL_HANDLER
Reporting after signal handler setup.
DESCRIPTION
This is encoded in the action argument and the return value for a report_signal() callback. It says what will happen to the signal
described by the siginfo_t parameter to the callback.
The UTRACE_SIGNAL_REPORT value is used in an action argument when a tracing report is being made before dequeuing any pending signal. If
this is immediately after a signal handler has been set up, then UTRACE_SIGNAL_HANDLER is used instead. A report_signal callback that uses
UTRACE_SIGNAL_DELIVER|UTRACE_SINGLESTEP will ensure it sees a UTRACE_SIGNAL_HANDLER report.

GUPNP_DEVICE_ACTION_CALLBACK_SET(3) 1 GUPNP_DEVICE_ACTION_CALLBACK_SET(3)gupnp_device_action_callback_set - Set device callback functionSYNOPSIS
bool gupnp_device_action_callback_set (resource $root_device, int $signal, string $action_name, mixed $callback, [mixed $arg])
DESCRIPTION
Set device callback function for signal and action.
PARAMETERS
o $root_device
- A root device identifier, returned by gupnp_root_device_new(3).
o $signal
- The value of signal. Signal can be one of the following values:
o GUPNP_SIGNAL_ACTION_INVOKED - Emitted whenever an action is invoked. Handler should process action and must call either
gupnp_service_action_return(3) or gupnp_service_action_return_error(3).
o GUPNP_SIGNAL_NOTIFY_FAILED - Emitted whenever notification of a client fails.
o $action_name
- The name of action.
o $callback
- The callback function for the certain signal. Typically, callback function takes on three parameters. The $service parameter's
identifier being the first, $action parameter's identifier (in case GUPNP_SIGNAL_ACTION_INVOKED signal) or $error parameter's mes-
sage (in case GUPNP_SIGNAL_NOTIFY_FAILED signal) being the second, and the $arg is third.
o $arg
- User data for $callback.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
ERRORS /EXCEPTIONS
Issues E_WARNING either with not valid callback function or with not valid signal.

Hi All,
When I ran a multithreaded program in c++, it was core dumped
when its core was analysed
it indicated that the program was terminated with signal 9.
Signal 9 cannot be caught or interrupted.
When i analyzed the core further, it showed SING error
