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).
