NAME

_exit − terminate a process

SYNOPSIS

_exit(status)
int status;

DESCRIPTION

_exit terminates a process with the following consequences:

All descriptors open in the calling process are closed. 

If the parent process of the calling process is executing a wait or is interested in the SIGCHLD signal, then it is notified of the calling process’s termination and the low-order eight bits of status are made avaliable to it; see wait(2). The low-order 8 bits of status are available to the parent process. 

The parent process ID of all of the calling process’s existing child processes are also set to 1.  This means that the initialization process (see intro(2)) inherits each of these processes as well.

Most C programs will 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.
