#include <keyutils.h> key_serial_t keyctl_join_session_keyring(const char *name);
If name is NULL then a new anonymous keyring will be created, and the process will be subscribed to that.
If name points to a string, then if a keyring of that name is available, the process will attempt to subscribe to that keyring, giving an error if that is not permitted; otherwise a new keyring of that name is created and attached as the session keyring.
To attach to an extant named keyring, the keyring must have search permission available to the calling process.
- Insufficient memory to create a key.
- The key quota for this user would be exceeded by creating this key or linking it to the keyring.
- The named keyring exists, but is not searchable by the calling process.
