stapvars - systemtap variables
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.
More files and their corresponding paths can be found in the
stappaths (7) manual page.
