keyctl_set_reqkey_keyring - set the implicit destination keyring
#include <keyutils.h> long keyctl_set_reqkey_keyring(int reqkey_defl);
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().
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.
EINVAL The value of reqkey_defl is invalid.
This is a library function that can be found in libkeyutils. When linking, -lkeyutils should be specified to the linker.
