/**
 * This program should open a file (file-name given on the command line,) and
 * write to it all the data that is read from the standard input.  You may only
 * use the kernel system calls for I/O, you may not use any C standard library
 * I/O calls.  The file opened should be created if it does not exist and
 * truncated if it does.  An error should be displayed if the file cannot be
 * opened and the program should return an non-successful return value.
 * 
 * This program should do I/O in blocks of at least 1K at a time, it is not
 * correct to read and write only 1 byte at a time.
