+<h3>SCANDIR(3) Linux Programmer's Manual SCANDIR(3)
+</h3>
+
+<h3>NAME
+</h3> scandir, alphasort - scan a directory for matching entries
+
+<h3>SYNOPSIS
+</h3> #include &lt;dirent.h&gt;
+
+ int scandir(const char *dir, struct dirent ***namelist,
+ int (*select)(const struct dirent *),
+ int (*compar)(const void *, const void *));
+
+ int alphasort(const struct dirent *a, const struct dirent *b);
+
+<h3>DESCRIPTION
+</h3> The scandir() function scans the directory dir, calling
+ select() on each directory entry. Entries for which
+ select() returns non-zero are stored in strings allocated
+ via malloc(), sorted using qsort() with the comparison
+ function compar(), and collected in array namelist which
+ is allocated via malloc().
+
+ The alphasort() function can be used as the comparison
+ function for the scandir() function to sort the directory
+ entries into alphabetical order. Its parameters are the
+ two directory entries, a and b, to compare.
+
+<h3>RETURN VALUE
+</h3> The scandir() function returns the number of directory
+ entries selected or -1 if an error occurs.
+
+ The alphasort() function returns 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.
+
+<h3>ERRORS
+</h3> ENOMEM Insufficient memory to complete the operation.
+
+<h3>CONFORMING TO
