       Read  directory  entries  from the directory specified by fd into buf.  At most nbytes are read.  Reading
       starts at offset *basep, and *basep is updated with the new position after reading.

       See the Linux library source code for details.

       getdirentries - get directory entries in a filesystem-independent format

       Use opendir(3) and readdir(3) instead.

getdirentries() returns the number of bytes read or zero when at the end of the directory.  If  an  error
       occurs, -1 is returned, and errno is set to indicate the error.
