Test Name: fstat.1 Failed

	Test Description:
A call to fstat() stores information about the file associated with
the named file descriptor in the area pointed to by buf and returns a
value of zero.

	Test Strategy:
CHECK st_dev, st_ino, S_ISREG(st_mode), st_size, st_atime, st_mtime
and st_ctime for a regular file as follows:
  CREATE file using crfile() - (genlib)
  OBTAIN time using time()
  SLEEP for 2 seconds using sleep()
  WRITE data to file using write()
  CLOSE file descriptor using close()
