    Command:

    keyctl_join_session_keyring

    
    
    

    SYNOPSIS

           #include <keyutils.h>
    
           key_serial_t keyctl_join_session_keyring(const char *name);
    
    
    

    DESCRIPTION

           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 avail-
           able, 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 per-
           mission available to the calling process.
    
    
    

    RETURN VALUE

           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.
    
    
    

    ERRORS

           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.
