        !            20: .I Scandir
        !            21: reads the directory
        !            22: .I dirname
        !            23: and builds an array of pointers to directory
        !            24: entries using
        !            25: .IR malloc (3).
        !            26: It returns the number of entries in the array and a pointer to the
        !            27: array through
        !            28: .IR namelist .
        !            29: .PP
        !            30: The
        !            31: .I select
        !            32: parameter is a pointer to a user supplied subroutine which is called by
        !            33: .I scandir
        !            34: to select which entries are to be included in the array.
        !            35: The select routine is passed a
        !            36: pointer to a directory entry and should return a non-zero
        !            37: value if the directory entry is to be included in the array.
        !            38: If
        !            39: .I select
        !            40: is null, then all the directory entries will be included.
        !            41: .PP
        !            42: The
        !            43: .I compar
        !            44: parameter is a pointer to a user supplied subroutine which is passed to
        !            45: .IR qsort (3)
        !            46: to sort the completed array. If this pointer is null, the array is not sorted.
        !            47: .I Alphasort
        !            48: is a routine which can be used for the
        !            49: .I compar
        !            50: parameter to sort the array alphabetically.
        !            51: .PP
        !            52: The memory allocated for the array can be deallocated with
        !            53: .I free
        !            54: (see
        !            55: .IR malloc (3))
        !            56: by freeing each pointer in the array and the array itself.

        !            63: Returns \-1 if the directory cannot be opened for reading or if

        !            65: cannot allocate enough memory to hold all the data structures.
