.SH DESCRIPCIÓN
La función \fBdirfd\fP() devuelve el descriptor de fichero asociado con el
flujo de directorio \fIdirp\fP.
.PP
This file descriptor is the one used internally by the directory stream.  As
a result, it is useful only for functions which do not depend on or alter
the file position, such as \fBfstat\fP(2)  and \fBfchdir\fP(2).  It will be
automatically closed when \fBclosedir\fP(3)  is called.
.SH "VALOR DEVUELTO"
On success, \fBdirfd\fP()  returns a file descriptor (a nonnegative integer).
On error, \-1 is returned, and \fIerrno\fP is set to indicate the cause of the
error.
.SH ERRORES
.\" glibc 2.8
POSIX.1\-2008 specifies two errors, neither of which is returned by the
current implementation.
.TP 
\fBEINVAL\fP
\fIdirp\fP does not refer to a valid directory stream.
.TP 
\fBENOTSUP\fP
The implementation does not support the association of a file descriptor
with a directory.
