TRACE_SIGNAL_OVERFLO(9) 					      SIGNAL						   TRACE_SIGNAL_OVERFLO(9)

NAME

       trace_signal_overflow_fail - called when signal queue is overflow

SYNOPSIS

       void trace_signal_overflow_fail(int sig, int group, struct siginfo * info);

ARGUMENTS

       sig
	   signal number

       group
	   signal to process group or not (bool)

       info
	   pointer to struct siginfo

DESCRIPTION

       Kernel fails to generate 'sig' signal with 'info' siginfo, because siginfo queue is overflow, and the signal is dropped. 'group' is not 0
       if the signal will be sent to a process group. 'sig' is always one of RT signals.

pcntl_sigwaitinfo - Waits for signals

SYNOPSIS

       int pcntl_sigwaitinfo (array  $set, [array  &$siginfo])

DESCRIPTION

	The pcntl_sigwaitinfo(3) function suspends execution of the calling script until one of the signals given in $set are delivered. If one of
       the signal is already pending (e.g. blocked by pcntl_sigprocmask(3)), pcntl_sigwaitinfo(3) will return immediately.

PARAMETERS

	      o $set
		- Array of signals to wait for.

	      o $siginfo
		- The $siginfo parameter is set to an array containing informations about the signal.  The following elements are set for all sig-
		nals:

		     osigno: Signal number

		     oerrno: An error number

		     ocode: Signal code

	       The following elements may be set for the SIGCHLD signal:

		     ostatus: Exit value or signal

		     outime: User time consumed

		     ostime: System time consumed

		     opid: Sending process ID

		     ouid: Real user ID of sending process

	       The following elements may be set for the SIGILL, SIGFPE, SIGSEGV and SIGBUS signals:

		     oaddr: Memory location which caused fault

	       The following element may be set for the SIGPOLL signal:

		     oband: Band event

		     ofd: File descriptor number

RETURN VALUES

	On success, pcntl_sigwaitinfo(3) returns a signal number.

EXAMPLES

       Example #1

	      pcntl_sigwaitinfo(3) example

	      <?php
	      echo "Blocking SIGHUP signal
";
	      pcntl_sigprocmask(SIG_BLOCK, array(SIGHUP));

	      echo "Sending SIGHUP to self
";
	      posix_kill(posix_getpid(), SIGHUP);

	      echo "Waiting for signals
";
	      $info = array();
	      pcntl_sigwaitinfo(array(SIGHUP), $info);
	      ?>
