NAME

       keyctl_set_reqkey_keyring - Set the implicit destination keyring

SYNOPSIS

       #include <keyutils.h>

       long keyctl_set_reqkey_keyring(int reqkey_defl);

DESCRIPTION

       keyctl_set_reqkey_keyring() sets the default destination for implicit key requests for the current thread
       and returns the old setting.

       After this operation has been issued, keys acquired by implicit key requests, such as might be  performed
       by  open()  on  an  AFS  or  NFS  filesystem,  will be linked by default to the specified keyring by this
       function.

       The valid values of reqkey_defl are:

       KEY_REQKEY_DEFL_NO_CHANGE
              This makes no change to the current setting.

       KEY_REQKEY_DEFL_THREAD_KEYRING
              This makes the thread-specific keyring the default destination.

       KEY_REQKEY_DEFL_PROCESS_KEYRING
              This makes the process-specific keyring the default destination.

       KEY_REQKEY_DEFL_SESSION_KEYRING
              This makes the session keyring the default destination.

       KEY_REQKEY_DEFL_USER_KEYRING
              This makes the UID-specific keyring the default destination.

       KEY_REQKEY_DEFL_USER_SESSION_KEYRING
              This makes the UID-specific session keyring the default destination.

       KEY_REQKEY_DEFL_DEFAULT
              This selects the default behaviour which is to use the thread-specific keyring if  there  is  one,
              otherwise  the process-specific keyring if there is one, otherwise the session keyring if there is
              one, otherwise the UID-specific session keyring.

       This setting is inherited across fork() and exec().

RETURN VALUE

       On success keyctl_set_reqkey_keyring() returns 0.  On error, the value -1 will be returned and errno will
       have been set to an appropriate error.

ERRORS

       EINVAL The value of reqkey_defl is invalid.

LINKING

       This  is  a  library  function  that  can  be  found  in libkeyutils.  When linking, -lkeyutils should be
       specified to the linker.
