                     23: the given file (mode 17) and sets up the buffer iobuf_____ (size 518(10) bytes);
                     24: putc____ and putw____ write a byte or word respectively
                     25: onto the file;
                     26: flush_____ forces the contents of the buffer to be written, but
                     27: does not close the file.
                     28: The format of the buffer is:

                     38: file creation failed; none of the other routines
                     39: return error information.
                     40: .sp
                     41: Before terminating, a program should call
                     42: flush_____ to force out the last of the output.
                     43: .sp
                     44: The user must supply iobuf_____, which should begin on a word boundary.
                     45: 
                     46: To write a new file using the same buffer, it
                     47: suffices to call flush_____, close the file,
                     48: and call fcreat______ again.
