 we just don't work on the same systems :


     When a file is opened with update mode (+ as the  second  or
     third character in the mode argument), both input and output
     may be performed on the associated stream.  However,  output
     must  not be directly followed by input without an interven-
     ing call to fflush(3C) or to a file positioning  function  (
     fseek(3C), fsetpos(3C) or rewind(3C)), and input must not be
     directly followed by output without an intervening call to a
     file   positioning  function,  unless  the  input  operation
     encounters end-of-file.
