KEYCTL_JOIN_SESSION_KEYRING(3) Key Management CallsL_JOIN_SESSION_KEYRING(3)
keyctl_join_session_keyring - join a different session keyring
#include <keyutils.h>
key_serial_t keyctl_join_session_keyring(const char *name);
keyctl_join_session_keyring() changes the session keyring to which a
process is subscribed.
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.
On success keyctl_join_session_keyring() returns the serial number of
the key it found or created. On error, the value -1 will be returned
and errno will have been set to an appropriate error.
ENOMEM Insufficient memory to create a key.
EDQUOT The key quota for this user would be exceeded by creating this
key or linking it to the keyring.
EACCES The named keyring exists, but is not searchable by the calling
process.
This is a library function that can be found in libkeyutils. When
linking, -lkeyutils should be specified to the linker.
