Unregisters a process from being critical to the system.
int ue_proc_register (pid)
pid_t pid; The ue_proc_unregister system call unregisters a particular process as being no longer critical to the system. A process that has been previously registered 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.
If the value of the pid parameter is equal to (pid_t) 0, the subroutine is unregistering the calling process.
The ue_proc_unregister service should be called only while executing with root authority in the user process.
