PROBE::SYSCALL_ANY(3stap)  Syscall Any Tapset  PROBE::SYSCALL_ANY(3stap)

NAME         top

       probe::syscall_any.return - Record exit from a syscall

SYNOPSIS         top

       syscall_any.return

VALUES         top

       syscall_nr
           number of the syscall

       retval
           return value of the syscall

       name
           name of the syscall

CONTEXT         top

       The process performing the syscall

DESCRIPTION         top

       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.
