NAME

       /proc/pid/syscall - currently executed system call

DESCRIPTION

       /proc/pid/syscall (since Linux 2.6.27)
              This  file  exposes  the  system  call number and argument registers for the system call currently
              being executed by the process, followed by the values of the stack  pointer  and  program  counter
              registers.   The  values of all six argument registers are exposed, although most system calls use
              fewer registers.

              If the process is blocked, but not in a system call, then the file displays -1  in  place  of  the
              system  call  number,  followed  by  just the values of the stack pointer and program counter.  If
              process is not blocked, then the file contains just the string "running".

              This file is present only if the kernel was configured with CONFIG_HAVE_ARCH_TRACEHOOK.

              Permission to access this file is governed by  a  ptrace  access  mode  PTRACE_MODE_ATTACH_FSCREDS
              check; see ptrace(2).
