       A stream is associated with an external file (which may be a physical
       device)  by opening a file, which may involve creating a new file.
       Creating an existing file causes its former contents to be discarded.
       If a file can support positioning requests (such as a disk file, as
       opposed to a terminal), then a file position indicator associated with
       the stream is positioned at the start of the file (byte zero), unless
       the file is opened with append mode.  If append mode is used, it is
       unspecified whether the position indicator will be placed at the start
       or the end of the file.  The position indicator is maintained by
       subsequent reads, writes, and positioning requests.  All input occurs
       as if the characters were read by successive calls to the fgetc(3)
       function; all output takes place as if all characters were written by
       successive calls to the fputc(3) function.

       A file is disassociated from a stream by closing the file.  Output
       streams are flushed (any unwritten buffer contents are transferred to
       the host environment)  before the stream is disassociated from the
       file.  The value of a pointer to a FILE object is indeterminate after a
       file is closed (garbage).

       A file may be subsequently reopened, by the same or another program
       execution, and its contents reclaimed or modified (if it can be
       repositioned at the start).  If the main function returns to its
       original caller, or the exit(3)  function is called, all open files are
       closed (hence all output streams are flushed)  before program
       termination.  Other methods of program termination, such as abort(3)
       do not bother about closing files properly.

       The stdio library is a part of the library libc and routines are
       automatically loaded as needed by cc(1).  The SYNOPSIS sections of the
       following manual pages indicate which include files are to be used,
       what the compiler declaration for the function looks like, and which
       external variables are of interest.
