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).
