NAME

       tapset::signal - systemtap signal tapset

DESCRIPTION

	 This family of probe points is used to probe signal activities.
	 Since there are so many signals sent to processes at any given
	 point, it is advisable to filter the information according to the
	 requirements.	For example, filter only for a particular signal
	 (if sig==2) or for a particular process (if pid_name==stap).

       signal.send
	      Signal being sent to a process

	       See probe::signal.send(3stap)
	       for details.

       signal.send.return
	      Signal being sent to a process completed (deprecated in SystemTap 2.1)

	       See probe::signal.send.return(3stap)
	       for details.

       signal.checkperm
	      Check being performed on a sent signal

	       See probe::signal.checkperm(3stap)
	       for details.

       signal.checkperm.return
	      Check performed on a sent signal completed

	       See probe::signal.checkperm.return(3stap)
	       for details.

       signal.wakeup
	      Sleeping process being wakened for signal

	       See probe::signal.wakeup(3stap)
	       for details.

       signal.check_ignored
	      Checking to see signal is ignored

	       See probe::signal.check_ignored(3stap)
	       for details.

       signal.check_ignored.return
	      Check to see signal is ignored completed
