KEYCTL_CHOWN(3)        Linux Key Management Calls        KEYCTL_CHOWN(3)

НАЗВАНИЕ

       keyctl_chown - change the ownership of a key

СИНТАКСИС

       #include <keyutils.h>

       long keyctl_chown(key_serial_t key, uid_t uid, gid_t gid);

ОПИСАНИЕ

       keyctl_chown() changes the user and group ownership details of a
       key.

       A setting of -1 on either uid or gid will cause that setting to
       be ignored.

       A process that does not have the SysAdmin capability may not
       change a key's UID or set the key's GID to a value that does not
       match the process's GID or one of its group list.

       The caller must have setattr permission on a key to be able to
       change its ownership.

ЗНАЧЕНИЕ ВОЗВРАТА

       On success keyctl_chown() returns 0 .  On error, the value -1
       will be returned and errno will have been set to an appropriate
       error.

ОШИБКИ

       ENOKEY The specified key does not exist.

       EKEYEXPIRED
              The specified key has expired.

       EKEYREVOKED
              The specified key has been revoked.

       EDQUOT Changing the UID to the one specified would run that UID
              out of quota.

       EACCES The key exists, but does not grant setattr permission to
              the calling process.
