NAME
keyctl_chown - Change the ownership of a key SYNOPSIS
#include <keyutils.h> long keyctl_chown(key_serial_t key, uid_t uid, gid_t gid); DESCRIPTION
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 change its ownership. RETURN VALUE
On success keyctl_chown() returns 0 . On error, the value -1 will be returned and errno will have been set to an appropriate error. ERRORS
ENOKEY The specied 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 EKEYREVOKED The specified key has been revoked.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. LINKING
This is a library function that can be found in libkeyutils. When linking, -lkeyutils should be specified to the linker. SEE ALSO

NAME
keyctl_set_timeout - Set the expiration timer on a key SYNOPSIS
#include <keyutils.h> long keyctl_set_timeout(key_serial_t key, unsigned timeout); DESCRIPTION
keyctl_set_timeout() sets the expiration timer on a key to timeout seconds into the future. Setting timeout to zero cancels the expira- tion, assuming the key hasn't already expired. When the key expires, further attempts to access it will be met with error EKEYEXPIRED. The caller must have setattr permission on a key to be able change its permissions mask. RETURN VALUE
On success keyctl_set_timeout() returns 0 . On error, the value -1 will be returned and errno will have been set to an appropriate error. ERRORS
ENOKEY The specied key does not exist. EKEYEXPIRED The specified key has already expired. EKEYREVOKED The specified key has been revoked. EACCES The named key exists, but does not grant setattr permission to the calling process. LINKING
