NAME

       stapvars - systemtap variables

DESCRIPTION

       The  following  sections  enumerate  the  public  variables  provided by standard tapsets installed, (the
       installation path is show in the stappaths (7) manual page).  Each variable is described with a type, and
       its behavior/restrictions.  The syntax is the same as printed with the stap option -p2.  Examples:

       example1:long
              Variable "example1" contains an integer.

       example2:string [long]
              Variable "example2" is an array of strings, indexed by integers.

   ARGV
       argc:long
              Contains the value of the $# value: the number of command line arguments passed to  the  systemtap
              script.  It is initialized with an implicit begin(-1) probe.

       argv:string [long]
              Contains  each command line argument as a string.  argv[1] will equal @1 if there was at least one
              command line argument.  Arguments beyond #32 are not transcribed, and produce  a  warning  message
              within the begin(-1) probe that initializes this array.

   NULL
       NULL:long
              Simply defined as the number 0.
