Registers a process as critical to the system.
int ue_proc_register (pid, argument) pid_t pid; int argument;
The ue_proc_register system call registers a particular process as critical to the system. A process that is critical will cause the system to terminate if that process has an unrecoverable hardware error associated with the process. Unrecoverable hardware errors associated with a process are determined by the kernel machine check handler on systems that support UE-Gard error processing.
An execed process from a critical process must register itself to be critical. A fork from a process inherits the critical registration unless the argument is set to NONCRITFORK.
If the value of the pid parameter is equal to (pid_t) 0, the subroutine is registering the calling process.
The ue_proc_register system call should be called only while executing with root authority in the user process.
| pid | Specifies the process' ID to be registered critical. |
| argument | Defined in the sys/proc.h header
file. Can be the following value:
|
The ue_proc_register system call can be called from the process environment only.
| 0 | Indicates successful completion. |
| EINVAL | Indicates that the pid parameter is not valid or the process no longer exists. |
| EACCES | Indicates that the caller does not have sufficient authority to alter the pid registration. |
