The low level probe handler type of the current probe.
See function::probe_type(3stap)
for details.
execname
Returns the execname of a target process (or group of processes)

for details.
pgrp Returns the process group ID of the current process
See function::pgrp(3stap)
for details.
sid Returns the session ID of the current process
See function::sid(3stap)
for details.
pexecname

for details.
gid Returns the group ID of a target process

for details.
egid Returns the effective gid of a target process
See function::egid(3stap)
for details.
uid Returns the user ID of a target process
See function::uid(3stap)
for details.
euid Return the effective uid of a target process
See function::euid(3stap)
for details.
is_myproc
Determines if the current probe point has occurred in the user's own process
See function::is_myproc(3stap)
for details.
cpuid Returns the current cpu number
See function::cpuid(3stap)
for details.
cpu Returns the current cpu number
See function::cpu(3stap)
for details.
registers_valid
Determines validity of register() and u_register() in current context
See function::registers_valid(3stap)
for details.
user_mode
Determines if probe point occurs in user-mode
See function::user_mode(3stap)
for details.
is_return
Whether the current probe context is a return probe
See function::is_return(3stap)
for details.
target Return the process ID of the target process
See function::target(3stap)
for details.
module_name
The module name of the current script
See function::module_name(3stap)
for details.
stp_pid
The process id of the stapio process
See function::stp_pid(3stap)
for details.
remote_id
The index of this instance in a remote execution.
See function::remote_id(3stap)
for details.
remote_uri
The name of this instance in a remote execution.
See function::remote_uri(3stap)
for details.
stack_size
Return the size of the kernel stack
See function::stack_size(3stap)
for details.
stack_used
Returns the amount of kernel stack used
See function::stack_used(3stap)
for details.
stack_unused
Returns the amount of kernel stack currently available
See function::stack_unused(3stap)
for details.
addr Address of the current probe point.
See function::addr(3stap)
for details.
uaddr User space address of current running task
See function::uaddr(3stap)
for details.
cmdline_args
Fetch command line arguments from current process
See function::cmdline_args(3stap)
for details.
cmdline_arg
Fetch a command line argument
See function::cmdline_arg(3stap)
for details.
cmdline_str
