+.In dirent.h
+.Ft int
+.Fn dirfd "DIR *dir"
+.Sh DESCRIPTION
+The
+.Fn dirfd
+function returns the file descriptor associated with the
+directory stream
+.Fa dir .
+.Lp
 This file descriptor is the one used internally by the directory stream
-operations. See \fBopendir\fR(3C), \fBclosedir\fR(3C), \fBreaddir\fR(3C),
-\fBrewinddir\fR(3C), \fBseekdir\fR(3C), \fBtelldir\fR(3C).  The file descriptor
-is automatically closed when \fBclosedir()\fR is called for the directory
-stream \fIdir\fR or when one of the \fBexec\fR functions is called.  See
-\fBexec\fR(2).

-.LP
+operations. See
+.Xr opendir 3C ,
+.Xr closedir 3C ,
+.Xr readdir 3C ,
+.Xr rewinddir 3C ,
+.Xr seekdir 3C ,
+and
+.Xr telldir 3C .
+The file descriptor
+is automatically closed when
+.Xr closedir 3C
+is called for the directory stream
+.Fa dir
+or when one of the
+.Xr exec 2
+functions is called.
+.Lp
 The file descriptor can safely be used only by functions that do not depend on
-or alter the file position, such as \fBfstat\fR(2) and \fBfchdir\fR(2).
-Closing the file descriptor with \fBclose\fR(2) or modifying the file position
+or alter the file position, such as
+.Xr fstat 2
+and
+.Xr fchdir .
+Closing the file descriptor with
+.Xr close 2
+or modifying the file position
 by means other than the directory stream operations listed above causes
 undefined behavior to occur when one of the directory stream operations is
-subsequently called with the directory stream \fIdir\fR.
-.SH RETURN VALUES
-.sp
-.LP
-Upon successful completion, the \fBdirfd()\fR function returns an open file
-descriptor for the directory associated with the directory stream \fIdir\fR.

+subsequently called with the directory stream
+.Fa dir .
+.Sh RETURN VALUES
+Upon successful completion, the
+.Fn dirfd
+function returns an open file
+descriptor for the directory associated with the directory stream
+.Fa dir .
+.Sh ERRORS
 There are no defined error returns.  Passing an invalid directory stream as an
-argument to the \fBdirfd()\fR function results in undefined behavior.
-.SH USAGE

-.LP
-The \fBdirfd()\fR function is intended to be used to obtain a file descriptor
-for use with the \fBfchdir()\fR function.
