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

 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.

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

signal.check_ignored

 for details.

signal.force_segv
Forcing send of SIGSEGV

 See  probe::signal.force_segv(3stap)

 for details.

signal.syskill
Sending kill signal to a process

 See  probe::signal.syskill(3stap)
