int64_t
arg0, ..., arg9
|
The first 10 input arguments to a probe represented as raw 64-bit
integers. If fewer than 10 arguments are passed to the current
probe, the remaining variables return zero. |
args[]
|
The typed arguments to the current probe, if any. args[]
array is accessed using an integer index, but each element is defined to be the type corresponding to the given probe argument. |
uintptr_t caller
|
The program counter location of the current thread just before
entering the current probe. |
chipid_t chip
|
The CPU chip identifier for the current physical chip. |
processorid_t cpu
|
The CPU identifier for the current CPU. |
cpuinfo_t *curcpu
|
The CPU information for the current CPU. |
lwpsinfo_t *curlwpsinfo
|
The lightweight process (LWP) state of the LWP associated with the
current thread. |
psinfo_t *curpsinfo
|
The process state of the process associated with the current thread. |
kthread_t *curthread
|
The address of the operating system kernel's internal data structure
for the current thread, the kthread_t.
kthread_t is defined in <sys/thread.h>. |
string
cwd
|
The
name of the current working directory of the process associated
with the current thread. |
uint_t
epid
|
The
enabled probe ID (EPID) for the current probe. This integer
uniquely identifies a particular probe that is enabled with a
specific predicate and set of actions. |
int
errno
|
The
error value returned by the last system call executed by this
thread. |
string
execname
|
The
name that was passed to exec(2)
to execute the current process. |
gid_t
gid
|
The
real group ID of the current process. |
uint_t
id
|
The
probe ID for the current probe. This ID is the system-wide unique
identifier for the probe as published by DTrace. |
uint_t
ipl
|
The
interrupt priority level (IPL) on the current CPU at probe firing
time. |
lgrp_id_t
lgrp
|
The
latency group ID for the latency group of which the current CPU
is a member. |
pid_t
pid
|
The
process ID of the current process. |
pid_t
ppid
|
The
parent process ID of the current process. |
string
probefunc
|
The
function name portion of the current probe's description. |
string
probemod
|
The
module name portion of the current probe's description. |
string
probename
|
The
name portion of the current probe's description. |
string
probeprov
|
The
provider name portion of the current probe's description. |
psetid_t
pset
|
The
processor set ID for the processor set containing the current
CPU. |
string
root
|
The
name of the root directory of the process associated with the
current thread. |
uint_t
stackdepth
|
The
current thread's stack frame depth at probe firing time. |
id_t
tid
|
The
thread ID of the current thread. For threads associated with user
processes, this value is equal to the result of a call to
pthread_self. |
uint64_t
timestamp
|
The
current value of a nanosecond timestamp counter. This counter
increments from an arbitrary point in the past and should only be
used for relative computations. |
uid_t
uid
|
The
real user ID of the current process. |
uint64_t
uregs[]
|
The current thread's saved user-mode register values at probe firing
time. |
uint64_t vtimestamp
|
The
current value of a nanosecond timestamp counter that is the
amount of time the current thread has been running on a CPU,
minus the time spent in DTrace predicates and actions. |
uint64_t walltimestamp
|
The current number of nanoseconds since 00:00 Universal Coordinated
Time, January 1, 1970. |
