Putback mode is a variant of get mode. In a filebuf, there is only one current position, instead of two separate get and put pointers. In get mode, the current position is that of gptr(); in put mode that of pptr(). The position in the buffer that corresponds to the position in external file system is normally _IO_read_end, except in putback mode, when it is _IO_save_end. If the field _fb._offset is >= 0, it gives the offset in the file as a whole corresponding to eGptr(). (?) PUT MODE: If a filebuf is in put mode, then all of _IO_read_ptr, _IO_read_end, and _IO_read_base are equal to each other. These are usually equal to _IO_buf_base, though not necessarily if we have switched from get mode to put mode. (The reason is to maintain the invariant that _IO_read_end corresponds to the external file position.) _IO_write_base is non-NULL and usually equal to _IO_base_base. We also have _IO_write_end == _IO_buf_end, but only in fully buffered mode. The un-flushed character are those between _IO_write_base and _IO_write_ptr. GET MODE: If a filebuf is in get or putback mode, eback() != egptr(). In get mode, the unread characters are between gptr() and egptr(). The OS file position corresponds to that of egptr(). PUTBACK MODE: Putback mode is used to remember "excess" characters that have been sputbackc'd in a separate putback buffer. In putback mode, the get buffer points to the special putback buffer. The unread characters are the characters between gptr() and egptr() in the putback buffer, as well as the area between save_gptr() and save_egptr(), which point into the original reserve buffer. (The pointers save_gptr() and save_egptr() are the values of gptr() and egptr() at the time putback mode was entered.) The OS position corresponds to that of save_egptr(). LINE BUFFERED OUTPUT: During line buffered output, _IO_write_base==base() && epptr()==base(). However, ptr() may be anywhere between base() and ebuf(). This forces a call to filebuf::overflow(int C) on every put. If there is more space in the buffer, and C is not a '\n', then C is inserted, and pptr() incremented. UNBUFFERED STREAMS: If a filebuf is unbuffered(), the _shortbuf[1] is used as the buffer. */ #define CLOSED_FILEBUF_FLAGS \ (_IO_IS_FILEBUF+_IO_NO_READS+_IO_NO_WRITES+_IO_TIED_PUT_GET) void attribute_compat_text_section _IO_old_file_init (fp) struct _IO_FILE_plus *fp; { /* POSIX.1 allows another file handle to be used to change the position of our file descriptor.
