stapvars - systemtap variables
The following sections enumerate the public variables provided by
standard tapsets installed under /usr/share/systemtap/tapset. Each
variable is described with a type, and its behavior/restrictions. The
syntax is the same as printed with the stap option -p2. Examples:
Variable "example1" contains an integer.
Variable "example2" is an array of strings, indexed by integers.
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.
Contains each command line argument as a string. argv 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.
Simply defined as the number 0.
