EXIT(2)EXIT(2)NAME
exit, _exit - terminate a process
SYNOPSIS
void _exit(int status)
DESCRIPTION
_exit terminates a process with the following consequences:
All of the descriptors open in the calling process are closed.
This may entail delays, for example, waiting for output to
drain; a process in this state may not be killed, as it is
already dying.
If the parent process of the calling process is executing a wait
or is interested in the SIGCHLD signal (Minix-vmd), then it is
notified of the calling process's termination and the low-order
eight bits of status are made available to it; see wait(2).
The parent process ID of all of the calling process's existing
child processes are also set to 1. This means that the initial‐
ization process (see intro(2)) inherits each of these processes
as well.
Most C programs call the library routine exit(3), which performs
cleanup actions in the standard I/O library before calling _exit.
RETURN VALUE
This call never returns.
