tapset::context - systemtap context tapset DESCRIPTION Context functions provide additional information about where an event occurred. These functions can provide information such as a backtrace to where the event occurred and the current register values for the processor. printregs Print a register dump See function::printregs(3stap) for details. pp Returns the active probe point See function::pp(3stap) for details. ppfunc Returns the function name parsed from pp() See function::ppfunc(3stap) for details. probetype The low level probe handler type of the current probe. See function::probetype(3stap) for details. execname Returns the execname of a target process (or group of processes) See function::execname(3stap) for details. pid Returns the ID of a target process See function::pid(3stap) for details. nspid Returns the ID of a target process as seen in a pid namespace See function::nspid(3stap) for details. tid Returns the thread ID of a target process See function::tid(3stap) for details. nstid Returns the thread ID of a target process as seen in a pid namespace See function::nstid(3stap) for details. ppid Returns the process ID of a target process's parent process See function::ppid(3stap) for details. nsppid Returns the process ID of a target process's parent process as seen in a pid namespace See function::nsppid(3stap) for details. pgrp Returns the process group ID of the current process See function::pgrp(3stap) for details. nspgrp Returns the process group ID of the current process as seen in a pid namespace See function::nspgrp(3stap) for details. sid Returns the session ID of the current process See function::sid(3stap) for details. nssid Returns the session ID of the current process as seen in a pid namespace See function::nssid(3stap) for details. pexecname Returns the execname of a target process's parent process See function::pexecname(3stap) for details. gid Returns the group ID of a target process See function::gid(3stap) for details. nsgid Returns the group ID of a target process as seen in a user namespace See function::nsgid(3stap) for details. egid Returns the effective gid of a target process See function::egid(3stap) for details. nsegid Returns the effective gid of a target process as seen in a user namespace See function::nsegid(3stap) for details. uid Returns the user ID of a target process See function::uid(3stap) for details. nsuid Returns the user ID of a target process as seen in a user namespace See function::nsuid(3stap) for details. euid Return the effective uid of a target process See function::euid(3stap) for details. nseuid Returns the effective user ID of a target process as seen in a user namespace See function::nseuid(3stap) for details. ismyproc Determines if the current probe point has occurred in the user's own process See function::ismyproc(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. registersvalid Determines validity of register() and uregister() in current context See function::registersvalid(3stap) for details. usermode
Determines if probe point occurs in user-mode See function::usermode(3stap) for details. isreturn Whether the current probe context is a return probe See function::isreturn(3stap) for details. target Return the process ID of the target process See function::target(3stap) for details. modulename The module name of the current script See function::modulename(3stap) for details. modulesize The module size of the current script See function::modulesize(3stap) for details. stppid The process id of the stapio process See function::stppid(3stap) for details. remoteid The index of this instance in a remote execution. See function::remoteid(3stap) for details. remoteuri The name of this instance in a remote execution. See function::remoteuri(3stap) for details. stacksize Return the size of the kernel stack See function::stacksize(3stap) for details. stackused Returns the amount of kernel stack used See function::stackused(3stap) for details. stackunused Returns the amount of kernel stack currently available See function::stackunused(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. cmdlineargs Fetch command line arguments from current process See function::cmdlineargs(3stap) for details. cmdlinearg Fetch a command line argument See function::cmdlinearg(3stap) for details. cmdlinestr Fetch all command line arguments from current process See function::cmdlinestr(3stap) for details.
