| PROBE::SYSCALL_ANY(3stap) | Syscall Any Tapset | PROBE::SYSCALL_ANY(3stap) |
NAME¶
probe::syscall_any.return - Record exit from a syscall
SYNOPSIS¶
syscall_any.return
VALUES¶
retval
return value of the syscall
name
name of the syscall
syscall_nr
number of the syscall
CONTEXT¶
The process performing the syscall
DESCRIPTION¶
The syscall_any.return probe point is designed to be a low overhead that monitors all the syscalls returns via a kernel tracepoint. Because of the breadth of syscalls it monitors it provides no information about the syscall arguments, argstr string representation of those arguments, or a string interpretation of the return value (retval).
This requires kernel 3.5+ and newer which have the kernel.trace(“sys_exit”) probe point.
