NAME
exit - terminate process
SYNOPSIS
exit(status)
int status;
_exit(status)
int status;
DESCRIPTION
Exit is the normal means of terminating a process. Exit closes all the
process's files and notifies the parent process if it is executing a
wait. The low-order 8 bits of status are available to the parent
process.
This call can never return.
The C function exit may cause cleanup actions before the final `sys
exit'. The function _exit circumvents all cleanup, and should be used
to terminate a child process after a fork(2) to avoid flushing buffered
output twice.
