.SH DESCRIPCIÓN
\fB_exit\fP()  terminates the calling process "immediately".  Any open file
descriptors belonging to the process are closed.  Any children of the
process are inherited by \fBinit\fP(1)  (or by the nearest "subreaper" process
as defined through the use of the \fBprctl\fP(2)  \fBPR_SET_CHILD_SUBREAPER\fP
operation).  The process's parent is sent a \fBSIGCHLD\fP signal.
.PP
The value \fIstatus & 0xFF\fP is returned to the parent process as the
process's exit status, and can be collected by the parent using one of the
\fBwait\fP(2)  family of calls.
.PP
La función \fB_Exit\fP() es equivalente a \fB_exit\fP().
.SH "VALOR DEVUELTO"
Estas funciones nunca regresan.
.SH ESTÁNDARES
POSIX.1\-2001, POSIX.1\-2008, SVr4, 4.3BSD. La función \fB_Exit\fP() fue
introducida por C99.
.SH NOTAS
Para una discusión sobre los efectos de una llamada exit, la transmisión de
estados de salida, procesos zombie, señales enviadas, etc., vea \fBexit\fP(3).
.PP
The function \fB_exit\fP()  is like \fBexit\fP(3), but does not call any functions
registered with \fBatexit\fP(3)  or \fBon_exit\fP(3).  Open \fBstdio\fP(3)  streams
are not flushed.  On the other hand, \fB_exit\fP()  does close open file
descriptors, and this may cause an unknown delay, waiting for pending output
to finish.  If the delay is undesired, it may be useful to call functions
like \fBtcflush\fP(3)  before calling \fB_exit\fP().  Whether any pending I/O is
canceled, and which pending I/O may be canceled upon \fB_exit\fP(), is
implementation\-dependent.
.SS "Diferencias núcleo / biblioteca C"
The text above in DESCRIPTION describes the traditional effect of
\fB_exit\fP(), which is to terminate a process, and these are the semantics
specified by POSIX.1 and implemented by the C library wrapper function.  On
modern systems, this means termination of all threads in the process.
.PP
.\" _exit() is used by pthread_exit() to terminate the calling thread
By contrast with the C library wrapper function, the raw Linux \fB_exit\fP()
system call terminates only the calling thread, and actions such as
reparenting child processes or sending \fBSIGCHLD\fP to the parent process are
performed only if this is the last thread in the thread group.
.PP
Up to glibc 2.3, the \fB_exit\fP()  wrapper function invoked the kernel system
call of the same name.  Since glibc 2.3, the wrapper function invokes
\fBexit_group\fP(2), in order to terminate all of the threads in a process.
