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.
