PR_MCE_KILL_SET(2const) PR_MCE_KILL_SET(2const)
PR_MCE_KILL_SET - set the machine check memory corruption kill
policy
Standard C library (libc, -lc)
#include <linux/prctl.h> /* Definition of PR_* constants */
#include <sys/prctl.h>
int prctl(PR_MCE_KILL, PR_MCE_KILL_SET, long pol, 0L, 0L);
Use a thread-specific memory corruption kill policy.
pol defines whether the policy is early kill (PR_MCE_KILL_EARLY),
late kill (PR_MCE_KILL_LATE), or the system-wide default
(PR_MCE_KILL_DEFAULT).
Early kill means that the thread receives a SIGBUS signal as soon
as hardware memory corruption is detected inside its address
space.
In late kill mode, the process is killed only when it accesses a
corrupted page. See sigaction(2) for more information on the
SIGBUS signal.
On success, 0 is returned. On error, -1 is returned, and errno
is set to indicate the error.
EINVAL pol is not a valid value.
