Expand description

prctl is a Linux-only API for performing operations on a process or thread.

Note that careless use of some prctl() operations can confuse the user-space run-time environment, so these operations should be used with care.

For more documentation, please read prctl(2).

Functions§

  • clear_mce_kill
    Clear the thread memory corruption kill policy and use the system-wide default
  • get_child_subreaper
    Get the “child subreaper” attribute for this process
  • get_dumpable
    Get the dumpable attribute for this process.
  • get_keepcaps
    Get the “keep capabilities” attribute for this process
  • get_mce_kill
    Get the thread memory corruption kill policy
  • get_name
    Return the name of the calling thread
  • get_no_new_privs
    Get the “no new privs” attribute for the calling thread.
  • get_pdeathsig
    Returns the current parent-death signal
  • get_thp_disable
    Get the “THP disable” flag for the calling thread.
  • get_timerslack
    Get the timerslack for the calling thread.
  • prctl_get_bool 🔒
  • prctl_set_bool 🔒
  • set_child_subreaper
    Set the “child subreaper” attribute for this process
  • set_dumpable
    Set the dumpable attribute which determines if core dumps are created for this process.
  • set_keepcaps
    Set the “keep capabilities” attribute for this process. This causes the thread to retain capabilities even if it switches its UID to a nonzero value.
  • set_mce_kill
    Set the thread memory corruption kill policy
  • set_name
    Set the name of the calling thread. Strings longer than 15 bytes will be truncated.
  • set_no_new_privs
    Set the calling threads “no new privs” attribute. Once set this option can not be unset.
  • set_pdeathsig
    Set the parent-death signal of the calling process. This is the signal that the calling process will get when its parent dies.
  • set_thp_disable
    Set the state of the “THP disable” flag for the calling thread. Setting this disables transparent huge pages.
  • set_timerslack
    Sets the timer slack value for the calling thread. Timer slack is used by the kernel to group timer expirations and make them the supplied amount of nanoseconds late.
  • set_vma_anon_name
    Set an identifier (or reset it) to the address memory range.
  • task_perf_events_disable
    Disable all performance counters attached to the calling process.
  • task_perf_events_enable
    Enable all performance counters attached to the calling process.
