                      3: This represents an otherwise invisble extension to the standard i/o
                      4: library to allow streams to be open with concurrent read/write
                      5: capabilities. To incorporate the changes, recompile all C routines
                      6: in the library with the new header.
                      7: 
                      8: Ammended manual pages are included.

                     12: [Note by Bill Joy: This is a modification of an (old) pdp-11 version
                     13: of the standard i/o library, but should go easily into the new stuff.
                     14: It has been used in a Modula Compiler for the PDP/11 version of UNIX.]

                     18: It should be noted that the structure _iobuf should be exactly like that
                     19: of the old structure, except for the addition of _delta, at the end. This
                     20: is because _doprint is usually coded in assembly language and need not be
                     21: changed if the field _delta (which it does not need to reference) is kept
                     22: at the end.  The structures vary from version 6 to VAX unix.
                     23:
