-.SH DESCRIPTION
-The
-.BR scandir ()
-function scans the directory \fIdirp\fP, calling
-\fIfilter\fP() on each directory entry.
-Entries for which
-\fIfilter\fP() returns nonzero are stored in strings allocated via
-.BR malloc (3),
-sorted using
-.BR qsort (3)
-with the comparison
-function \fIcompar\fP(), and collected in array \fInamelist\fP
-which is allocated via
-.BR malloc (3).
-If \fIfilter\fP is NULL, all entries are selected.
-.P
-The
-.BR alphasort ()
-and
-.BR versionsort ()
-functions can be used as the comparison function
-.IR compar ().
-The former sorts directory entries using
-.BR strcoll (3),
-the latter using
-.BR strverscmp (3)
-on the strings \fI(*a)\->d_name\fP and \fI(*b)\->d_name\fP.
-.SS scandirat()
-The
-.BR scandirat ()
-function operates in exactly the same way as
-.BR scandir (),
-except for the differences described here.
-.P
-If the pathname given in
-.I dirp
-is relative, then it is interpreted relative to the directory
-referred to by the file descriptor
-.I dirfd
-(rather than relative to the current working directory of
-the calling process, as is done by
-.BR scandir ()
-for a relative pathname).
-.P
-If
-.I dirp
-is relative and
-.I dirfd
-is the special value
-.BR AT_FDCWD ,
-then
-.I dirp
-is interpreted relative to the current working
-directory of the calling process (like
-.BR scandir ()).
-.P
-If
-.I dirp
-is absolute, then
-.I dirfd
-is ignored.
-.P
-See
-.BR openat (2)
-for an explanation of the need for
-.BR scandirat ().
-.SH RETURN VALUE
-The
-.BR scandir ()
-function returns the number of directory entries
-selected.
-On error, \-1 is returned, with
-.I errno
-set to indicate the error.
-.P
-The
-.BR alphasort ()
-and
-.BR versionsort ()
-functions return an integer less than, equal to,
-or greater than zero if the first argument is considered to be
-respectively less than, equal to, or greater than the second.
-.SH ERRORS
-.TP
-.B EBADF
-.RB ( scandirat ())
-.I dirp
-is relative but
-.I dirfd
-is neither
-.B AT_FDCWD
-nor a valid file descriptor.
-.TP
-.B ENOENT
-The path in \fIdirp\fR does not exist.
-.TP
-.B ENOMEM
-Insufficient memory to complete the operation.
-.TP
-.B ENOTDIR
-The path in \fIdirp\fR is not a directory.
-.TP
-.B ENOTDIR
-.RB ( scandirat ())
-.I dirp
-is a relative pathname and
-.I dirfd
-is a file descriptor referring to a file other than a directory.

-POSIX.1-2008.

-GNU.
-.SH HISTORY
-.TP
-.BR alphasort ()
-.TQ
-.BR scandir ()
-4.3BSD, POSIX.1-2008.
-.TP
-.BR versionsort ()
-glibc 2.1.
-.TP
-.BR scandirat ()
-glibc 2.15.
-.\" .P
-.\" The functions
-.\" .BR scandir ()
-.\" and
-.\" .BR alphasort ()
-.\" are from 4.3BSD, and have been available under Linux since libc4.
-.\" Libc4 and libc5 use the more precise prototype
-.\" .sp
-.\" .nf
-.\"    int alphasort(const struct dirent ** a,
-.\"                  const struct dirent **b);
-.\" .fi
-.\" .sp
-.\" but glibc 2.0 returns to the imprecise BSD prototype.
-.SH NOTES
-Since glibc 2.1,
-.BR alphasort ()
-calls
-.BR strcoll (3);
-earlier it used
-.BR strcmp (3).
-.P
-Before glibc 2.10, the two arguments of
-.BR alphasort ()
-and
-.BR versionsort ()
-were typed as
-.IR "const void\ *" .
-When
-.BR alphasort ()
-was standardized in POSIX.1-2008,
-the argument type was specified as the type-safe
-.IR "const struct dirent\ **",
-and glibc 2.10 changed the definition of
-.BR alphasort ()
-(and the nonstandard
-.BR versionsort ())
-to match the standard.
-.SH EXAMPLES
-The program below prints a list of the files in the current directory
-in reverse order.
