STAPVARS(3stap) 														   STAPVARS(3stap)

NAME

       stapvars - systemtap variables

DESCRIPTION

       The  following  sections enumerate the public variables provided by standard tapsets installed, (the installation path is show in the stap-
       paths(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.
