NAME         top

       keyctl_set_reqkey_keyring - Set the implicit destination keyring

SYNOPSIS         top

       #include <keyutils.h>

       long keyctl_set_reqkey_keyring(int reqkey_defl);

DESCRIPTION         top

       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         top

       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         top

       EINVAL The value of reqkey_defl is invalid.

LINKING         top

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