KEYCTL_SET_TIMEOUT(3)					    Linux Key Management Calls					     KEYCTL_SET_TIMEOUT(3)

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	      The specified key has been revoked.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

       This is a library function that can be found in libkeyutils.  When linking, -lkeyutils should be specified to the linker.
