KEYCTL_SET_TIMEOUT(3) Linux Key Management Calls KEYCTL_SET_TIMEOUT(3)
keyctl_set_timeout - set the expiration timer on a key
#include <keyutils.h>
long keyctl_set_timeout(key_serial_t key, unsigned timeout);
keyctl_set_timeout() sets the expiration timer on a key to
timeout seconds into the future. Setting timeout to zero cancels
the expiration, 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 to
change its permissions mask.
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.
ENOKEY The specified 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The specified key has been revoked.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.
This is a library function that can be found in libkeyutils.
When linking, -lkeyutils should be specified to the linker.
